arguments. � The default values can be included in the function prototype form right to left i.e.,

we cannot have a default value for an arguments in between the arguments. 18. Write notes on returning values in function?

The functions that return no value is declared as void. The data type of a function is treated as int , if no data type is explicitly mentioned. For example: int add (int a, int b); add(int a, int b); In both prototypes, the return value is int. Because by default the return value of a function in C++ is of type int.

Important Questions and Answers 1. What is class and give example?

The most important feature of C++ is the class. A class is a new way of creating and implementation a user defined data type. Classes provide a method for packing together data of different types. A class is a way to bind data and its associated functions together. Example: class student { char name[30]; int rno,m1,m2, total; };

2. What are the two types of a class specification? � A class specification has two parts

o Class declaration o Class function definition

3. Write the general format of Class?

CHAPTER-6: Classes and Objects

class class_name { private: variable declaration; function declaration; protected: variable declaration; function declaration; public: variable declaration; function declaration; };



4. What is encapsulation? The binding of data and functions together into a single entity is called as encapsulation.

5. What is data hiding? � Data hiding is the key features of OOPS. � The members and functions declared under private are not accessible by outside the

class, this is called as Data hiding. 6. What is Data Abstraction?

� Instruments allowing only selected access of components to objects and to members of other classes is called as data abstraction.

� Data abstraction is achieved through data hiding. 7. What are the two methods to create the objects?

� In C++ the class variables are known as objects. � The declaration of an object is similar to that of a variable of any basic type.

1. Student s; This statement may be read as s is an instance or object of the class student.

2. Objects can also be created by placing their names immediately after brace of the class declaration. Ex: class student { private: protected: public: } S; //Here S is an object

8. What are the three access specifiers in a class? The class body has three access specifiers, They are

o Private: The members that have been declared as private can be accessed only from within the class.

o Protected: The members that have been declared as protected, can be accessed from the class and the members of the inherited class

o Public: The members that have been declared as public can be accessed from outside the class also.

9. Define Static Data members? The static variable:

� Is initialized to zero, only when the first object of its class is created. No other initialization is permitted.

� Only one copy of the member variable is created(as part of the common pool) and is shared by all the other objects of its class type.

� Its scope or visibility is within the class but its lifetime is the lifetime of the program 10. What does a class comprise?

A class comprises of data members and member functions.



11. What is array of objects? We can create group of objects of same class at same time. It is called as Array of objects. Ex: class add { :::::::::::

}s[5]; array of objects 12. How to accessing the class members?

The members of a class are accessed using the dot operator. For example, the call statement to the function execute( ) of the class student may be given as stud . execute( ); Member function Dot Operator

Object name 13. What are the special characteristics of Member function? (Or) List any four

characteristics of member function used in program development � Several different class can use the same function name. The membership label will

resolve their scope. � Member function can access the private data of class. A non member function

cannot do so. � A member function can call another member function directly without the dot

operator is called nesting of member function. � The member functions can receive the arguments of a valid C++ data type. Objects

can also be passed as arguments. � The return type of a member function can be of object data type. � Member functions can be of static type.

14. How are the memory allocation of objects? � The member functions are created and placed in the memory space only when they

are defined as a part of the class specification. � All the objects belonging to that class use the same member function. � No separate space is allocated for member function when the objects are created. � Memory space is allocated for the member variable separately for each object. � Separate memory allocation for objects are essential because the member variables

will hold different data values for different objects. 15. What is Data members and Member function?

Class comprises of members. Members are classified as data members and member functions.

Data Members Member function 1. Data members are the data variable

that represent the features or properties of a class.

2. Data members are also called as attributes.

1. Member function are the functions that perform specific task in a class.

2. Member functions are also called as methods.



16. What is the use of membership label? The membership label class_name:: tell the compiler that the function function_name belongs to the class class_name. Ex: void add :: display( ); Member function Scope resolution operator Class Name Data type of the member fucntion Here add:: is class label

17. What is the nesting of member function? A member function can call another member function directly without using the dot operator is called nesting of member function.

18. How will you define methods of a class? In two ways we can define methods of a class

o Inside the class declaration o Outside the class declaration

Inside the class declaration: The member functions defined within the class behave like inline function. Ex: class add { int a,b; public: add( ) { a=0; b=0; } void display( ) { cout<<”computer”; } }; Here the member function display( ) is declared and defined within the class add. Outside the class declaration: Member function defined outside the class has the prototype as Type classname::function name( );



Ex: class add { int a,b; public: void display( ); }; void add:: display( ) { cout<<”Computer”; } Here the member function display( ) is declared inside the class and defined outside the class add.

19. Write notes on class declaration?

The keyword class specifies user defined data type class name. The body of a class enclosed within braces and is terminated by a semicolon. The class body contains the declaration of variable and functions. The class body has three access specifiers (visibility labels) viz., private, protected, public. Specifying private visibility label is optional. By default the memerbs will be treated as

private if visibility label is not mentioned. The members that have been declared as private can be accessed only from within the

class. The members that have been declared as protected, can be accessed from the class and the

members of the inherited class. The members that have been declared as public can be accessed from outside the class

also.

class class_name

{

private:

variable declaration;

function declaration;

protected:



public:



};



Important Questions and Answers 1. What is function overloading?

2. What is operator overloading? � The term operator overloading, refers to giving additional functionality to the

normal C++ operators like +,++,-,--,+=,-=,*,<,>. [Or]

� The mechanism of giving special meaning to an operator is called as operator overloading.

3. How are functions are invoked in function overloading? The compiler adopts BEST MATCH strategy. As per this strategy, the compiler will

� Look for the exact match of a function prototype with that of a function call statement.

� In case an exact match is not available, it looks for the next nearest match. That is, the compiler promote integral data promotions and then match the call statement with function prototype.

4. What are the rules for function overloading? � Each overloaded function must differ either by the number of its formal parameters

or their data types. � The return type of overloaded functions may or may not be the same data type. � The default arguments of overloaded functions are not considered by the C++

compiler as part of the parameter list. � Do not use the same function name for two unrelated functions.

5. Mention any two rules for operator overloading? � Only existing operators can be overloaded. New operators cannot be created. � The overloaded operator must have at least one operand of user defined type.

12. What are the advantages of operator overloading? (Or) What does operator overloading provides? New function definitions for basic C++ operators like +,*,-,++,--,>,<,+= and the like. The following operators cannot be overloaded.

o : : Scope resolution operator o . dot operator o ? conditional operator o Sizeof( ) operator

The overloaded function definitions are permitted for user defined data type. The operator functions must be either member functions or friend functions. The new definition that is provided to an operator does not overrule the original definition of the operator.



Important Questions and Answers 1. What are the functions of constructor?

4. What are the rules for destructor definition and usage? The destructor has that same name as that of class prefixed by the tilde character(~). The destructor cannot have parameter list. It has no return type. Destructor cannot be overloaded i.e., there can be only one destructor in a class. In the absence of user defined destructor, it is generated by the compiler. The destructor is executed automatically when the control reaches the end of class scope.

It is declared under the public part. 5. What are the difference between constructor and destructor?

Constructor Destructor 1. The functions of a constructor is

initialized the class object. 2. Constructor is executed when an

object is created. 3. Constructor can be overloaded. 4. A class can have multiple constructor.

declared. 9. What is destructor?

� A destructor is a function that removes the memory of an object which was allocated by the constructor at the time of creating a object.

� It carries the same name as the class name, but with a tiled (~) as prefix. Ex:

class simple

{

…………….

…………….

Public:

Simple ( )

{

………

..…….

}

};

class simple

{

…………….

Public:

~simple ( )

{

……………

}

};



10. What are the similarities between constructor and destructor? Both are declared under public part. Both the function return nothing. They are not associated with any data type. Both has the same name as that of the class.

1. The efficiency and correctness of data processing are limited to the capabilities of the

individual who is processing the data.

2. Manual methods take more time.

3. In general human beings are liable to make computational and parallax errors.

4. Manual data processing involves use of papers at each stage. Preservation and

maintenance of large volume of paper records becomes difficult and unmanageable.

5. Implementation of corrections, changes and modification are tedious in manual data

processing.

2. What are the advantages of computerized data processing?

1. Once we can collect and enter the data into a computer system we can perform other

operations with less manual labour. So manpower is considerable saved.

2. Though it takes some time to develop, test and put the required computer programs to

use, the processing speed is fast, reducing the processing time, in certain cases, from

man-years and man-months to minutes and seconds.

3. The changes of errors are less in computerized data processing.

4. We can store large amount of the data and information in the computer storage

medium, which is compact. Hence we need not store bundles of paper records thus

saving space.

5. Today computer networks are so common that we can share data and resources from

one computer system to the other at a very fast speed and with very little effort, as in

the case of railway and airline reservation systems.

1. Searching: Searching is a process to select a desired specific data from a database. For example We want to select the student ranking first in a class with respect to the total marks.

2. Sorting: Sorting is the process of arranging the data in a table in some order. For example we may arrange the students name in alphabetical order.

3. Merging: Merging is a process of joining data from two or more tables of the same or different databases.

4. Performing calculations on Data: We may do any kind of arithmetic calculations on the data stored in the database. For Example to obtain the total marks of all the subjects of student, you may add the marks in the concerned fields of the database and store them in a separate field.

5. Filtering: There are times when viewing the entire table is unwieldy. Using a Filter is a way of limiting the information that appears on screen. Filters are a feature for displaying and browsing a selected list or subset of records from a table. The visible records satisfy the condition. Those do not satisfy the condition are hidden.

6. Editing the Database: Editing is a process of performing corrections on the existing data, deleting the existing data, fields, or records , adding new data, fields, records. Changing the database format and so on.

7. Report Generation: � Report is a printed information on the paper. � We may generate any desired report, from the data of the database. For example in the

2. Relational Database: A relational structure represents a database made up of a set of related tables. In a relational database one or more common fields existing in two or more tables create a relationship between these tables. The common field of fields are called the keys.

A primary key is a key that uniquely identifies a record in a database table.

The relational database structures is the most prevent database in today’s business organizations.

3. Hierarchical database: The hierarchical database structures were primarily used on Main Frame computers. In hierarchical databases, records are organized in a tree like structure by type. The relationship between record is said to be a parent-child relationship, in which any child type relates only to a single parent type. 4. Network Database:

The network database is very similar to the hierarchical structure except that any one record type can relate to any number of other record types.

5. Object Oriented Database: � An Object oriented database is a newer structure that has been generating a great deal of

interest in recent types.

� The object oriented structure groups data items and their associated characteristics, attributes and procedures into complex items called as Objects.

� An object is defined by its characteristics, attributes and procedures. An objects

characteristics can be text, sound, video. Examples of attributes might be color, size, and style. A procedure refers to the processing or handling that can be associated to the object.

2. What is Loop? Explain loops in C++. [Or] Explain any one loop in C++ with example. Loop: Loops execute a set of instructions repeatedly for a certain number if times. There are three kinds of loops in C++.

1. For ( ) 2. While( ) 3. Do…….While( )

1. For ( ): It is a entry controlled loop and is used when an action is to be repeated for a

predetermined number of times. The general syntax is

Example:

for(i=1;i<5;i++) Increment Test Condition Initialization

The general working of for( ) loop is

1. Enter the loop. 2. Initializes the control variable num to 2. 3. The test condition is (num<=6) is evaluated if the text condition is true. 4. Print the square of num. 5. Increments num by 1. 6. Control is transferred to step 3. 7. End.

for (initial value; condition; increment)

{

action block;

}


#include<conio.h>

void main( )

{

for(int num=2;num<=6;num++)

cout<<num*num;

getch( );

}



2. While( ): Definition: It is called as the entry-check loop. The body of the loop will be executed only if the test expression results true placed in the while statement. The control exits the loop once the test expression is evaluated to false.

The general syntax is Example Program:


8. Enter the loop. 9. Initializes the control variable num to 2. 10. The test condition is (num<=6) is evaluated if the text condition is true. 11. Print the square of num. 12. Increments num by 1. 13. Control is transferred to step 3. 14. End

while (condition)

{

action block;

}


#include<conio.h>

void main( )

{

int num=2;

while(num<=6)

{

cout<<num*num;

num+=1;

}

getch( );

}



3. Do…..while( ): Definition: It is called as exit-check loop, as the condition marks the last statement of the body of the loop.

The general syntax is

Example program:


1. Enter the loop. 2. Initializes the control variable num to 2. 3. Print the square of num. 4. Increments num by 1. 5. The test condition is (num<=6) is evaluated if the text condition is true. 6. Control is transferred to step 3. 7. End

do

{

action block;

} while (condition);


#include<conio.h>

void main( )

{

int num=2;

do

{

cout<<num*num;

num+=1;

} while(num<=6);

getch( );

}



3. Explain Switch Statement with an example. Definition: It is a multiple branching statement where based on a condition, the control is transferred to one of the many possible points. The general syntax is

4. Explain Nested… If Statement with example. Nested…If Statement:

Definition: 1. The statement sequence of if or else may contain another if statement. The If…Else

statement can be nested within another. 2. In an nested if…….else statement, “Each else matches with the nearest unmatched

preceding if”. The general syntax is

Example Program:


1. m1>70 and m2>70, then pass will be printed 2. m1>70 and m2<70, then fail will be printed. 3. m1<70, the inner if will not be executed, the

outer else will be executed and thus prints “Try to get pass”.

if(condition)

if(condition)

{

action block-1;

}

else

{

action block-2;

}

else

{

action block-3;

}


#include<conio.h>

void main( )

{

int m1,m2;

cout<<”Enter the values of m1 and m2”;

cin>>m1>>m2;

if(m1>70)

if(m2>70)

{

cout<<”Pass”;

}

else

{

cout<<”Fail”;

}

else

{

cout<<”Try to get pass”;

}

getch( );

}



Question No: 107 (Functions) [Lesson No: 4]

1. Explain about to how calling a function with an example? A function can be called or invoked from another function by using its name. The function name may include a set of actual parameters, enclosed in parentheses separated by comma.

Formal Parameters

Actual Parameters Working of a function


#include<conio.h>

int add(int a , int b)

{

return a+b;

}

void main( )

{

int x1,x2,sum=0;

cin>>x1>>x2;

sum=add(x1,x2);

cout<<sum;

getch( );

}

int add (int , int )

…….

return a+b;

}

void main( )

{

……….

Sum=add(x1,x2);

cout<<sum;

}



2. Explain Call by value and Call by reference with an example. Call by Value: 1. In this method, the called function creates new variables to store the value of the

arguments passed to it. 2. This method copies the values of actual parameters into the formal parameters. 3. Thus the function creates its own copy of arguments and then uses them. Example:

Ouput:

10 20

20 10

10 20


#include<conio.h>

void swap(int a, int b)

{

int temp;

temp=a;

a=b;

b=temp;

cout<<a<<’\t’<<b;

}

void main( )

{

int m1=10,m2=20;

cout<<m1<<’\t’<<m2;

swap(m1,m2);

cout<<m1<<’\t’<<m2;

getch( );

}

In Call by value method, any change in the formal parameter is not reflected back to the actual parameter.



Call by Reference: 1. In this method, the called function arguments-formal parameters become alias to the

actual parameters in the calling function. 2. This means that when the function is working with its own arguments, it is actually

working on the original data.

Example:

Output:

10 20

20 10

20 10


#include<conio.h>

void swap(int &a, int &b)

{

int temp;

temp=a;

a=b;

b=temp;

cout<<a<<’\t’<<b;

}

void main( )

{

int m1=10,m2=20;

cout<<m1<<’\t’<<m2;

swap(m1,m2);

cout<<m1<<’\t’<<m2;

getch( );

}

In call by reference method, any change made in the formal parameter is reflected back in the actual parameter.



3. What are the rules for actual parameters?

1. The actual parameters can be passed in the form of constants, variables or expressions to the formal parameters which are of value type. For example, For a function prototype int add(int a , int b) the call statements may be as follows x=add(5,10); x=add((5+10),3); x=add(a1,a2); Where a1,a2 are variables.

2. The actual parameters can be passed only as variables to formal parameters of reference type. For example, int add(int &a , int &b) The call statements as follows X=add(a1,a2); Where a1,a2 are variables. The following call statements are invalid: X=add((a1+b1),a1); X=add(5,10)



4. What is inline function? Explain with an example?

Example:

As shown in the above example, the call statement to the function convert_feet(inches) will be replaced by the expression in the return statement inches*12.

� To make a function inline, one has to insert the keyword inline in the function header.

Note:

� Inline keyword is just a request to the compiler. Sometimes the compiler will ignore the request and treat as a normal function and vice versa.

An Inline looks like a normal function in the source file but inserts the function’s code directly into the calling program. Inline function execute faster but require more memory space.


#include<conio.h>

inline float convert_feet(int x)

{

return x*12;

}

void main( )

{

int inches=45;

cout<<convert_feet(inches);

getch( );

}



5. What is scope? Explain the types of scope with programs. Scope: Scope refers to the accessibility of a variable. 1. Local scope 2. Function scope 3. File Scope 4. Class Scope 1. Local Scope:

1. A local variable is defined within a block. 2. The scope of a local variable is the block in which it is defined. 3. A local variable cannot be accessed from outside the block of its declaration. 4. Local variables are not known outside their own code block. A block of code begins

and ends with curly braces { }. 5. Local variables exist only while the block of code in which they are declared is

executed. 2. Function Scope:

The scope of variables declared within a function is executed to the function block, and all sub blocks there in. The life time of a function scope variable is the life time of the function block. The scope of formal parameters is function scope.

3. File Scope: A variable declared I above all blocks and functions above main( ) ahs to the scope of file. The scope of a file scope variable is the entire program. The lifetime of a file scope variable is lifetime of a program.

Example:

#include<iostream.h> #include<conio.h> int a=10; File scope void main( ) { int a=4,b=7; { int c; Function Scope c=a+b; cout<<c; Local Scope } }



4. Class Scope: 1. The members that have been declared as private can be accessed only from within

the class. 2. The members that have been declared as protected can be accessed from within the

class, and the members of the inherited classes. 3. The members that have been declared as public can be accessed from outside the

class also.

Class class_name

{

private:



protected:



public:



};



Question No: 108[Polymorphism-Lesson No: 7]

1. What is function overloading? Explain with an example.

Example:

float area( float a);

float area( float a, float b);

float area( float a, float b, float c);

The first prototype had one argument, second prototype had two arguments and

third prototype had three arguments.

Rules for function Overloading:

1. Each overloaded function must differ either by the number of its formal parameters or their data types.

2. The return type of overloaded functions may or may not be the same data type. 3. The default arguments of overloaded functions are not considered by the C++ compiler as part

of the parameter list. 4. Do not use the same function name for two unrelated functions.

Example program:

The ability of the function to process the message or data in more than one form is called as function over loading.


#include<conio.h>

int add( int a ,int b)

{

return a+b;

}

int add(int a, int b, int c)

{

return a+b+c;

}

void main( )

{

cout<<add(10,20);

cout<<add(10,20,30);

}



2. What is operator overloading? Explain with an example.

The function void operator-( ) simply negates the data members of the class as one would with a normal variable as follows: sum=-num1;

The term operator overloading, refers to giving additional functionality to the normal C++ operators like +,++,-,--,+=,-=,*,<,>.

[Or]

The mechanism of giving special meaning to an operator is called as operator overloading.


#include<conio.h>

class negative

{

int i;

public:

void accept( )

{

cout<<”\n Enter the number”;

cin>>i;

}

void display( )

{

cout<<”\n Number…”<<i;

}

void operator-( )

{

i = - i;

}

};

void main( )

{

negative n2;

n2.accept( );

-n2;

n2.display( );

}



3. What are the rules for operator overloading? 1. Only existing operators can be overloaded. New operators cannot be created. 2. The overloaded operator must have at least one operand of user defined type. 3. The basic definition of an operator cannot be replaced or in other words on

cannot redefine the function of an operator. One can give additional functions to an operator.

4. Overload operators behave in the same way as the basic operators in terms of their operands.

5. When binary operators are overloaded, the left hand object must be an object of the relevant class.

6. Binary operators overloaded through a member function take one explicit argument.

4. Explain the different types of inheritance? Classes can be derived from that are themselves derived. These are five types of inheritance in C++ They are

o Single Inheritance o Multiple Inheritance o Multilevel Inheritance o Hybrid Inheritance o Hierarchical Inheritance

1) Single Inheritance:

When a derived class inherits only from one base class, it is known as single inheritance.

Base Class-Employee

Derived Class-Employee



2) Multiple Inheritance: When a derived class inherits from multiple base classes it is known as multiple inheritance.

3) Multilevel Inheritance:

The transitive nature of inheritance is reflected by this form of inheritance. When a class is derived from a class which is a derived class itself-them this is reflected to as multilevel inheritance.

Base Class-Address Base Class-Office

Derived Class-Manager

Base Class-Grand Father

Derived Class-Father

Derived Class-Child

Invalid Construct

if a > b

if ( a > b)

a--;

cout<<”\n decremented”;

else

a++;

cout<<”\n Incremented”;

Error thrown by the compiler is

“Misplaced Else”.

If( a > b);

cout<<” Greater”;

cout<<” Lesser”;

Error thrown by the compiler is

“Misplaced Else”.

Valid Construct

if ( a>b )

Condition should always be enclosed in a

pair of brackets

if ( a > b)

{

a--;

cout<<”\n Decremented”;

}

else

{

a++;

cout<<”\n Incremented”;

}

If the action block is compound statements,

then it should be enclosed in curly braces

If( a > b)

cout<<” Greater”;

else

cout<<” Lesser”;

The semicolon don’t placed after the

condition.

Char name[ ]= “shiv”;

Switch(name)

{

case “shiv” : cout<<” Shiva Secured 1st Rank”;

break;

case “Rama”:cout<<”Rama Secured 2nd Rank”;

break;

}

Compiler throws an error “Switch selection expression must be of integral type” which

means that switch expression should be evaluate integer constant only (char, enum, int)

float value;

switch(value)

{

case 1.5: cout<<value-0.5;

break;

case 2.9: cout<<value+0.5;

The size of a 2-D array is calculated as follows:

1. int sales[4][4];

Number of Elements = Rows x Columns

= 4 x 4

= 16

Memory Size = 16 x 2 (2 bytes is required for integer)

= 32 bytes

2. float [4][6];


= 4 x 6

= 24

Memory Size = 24 x 4 (4 bytes is required for float)

= 96 bytes

3. char name[10][7];


= 10 x 7

= 70

Memory Size = 70 x 1 (1 byte is required for char)

= 70 bytes
