Practical Programs of C++

List of all programs in Sem 4

1. Reverse of a Number

2. Factorial of a Number

3. Switch program for :

a. Sin

b. Cos

c. Factorial

d. Power

e. Square root of a Number.

4. Palindrome of a Number.

5. Write A Program (WAP) using class student which has

access specified as public and the name of function

getmarks() and totalmarks() of 2 subjects. Thisprogram will accept marks of two subjects (using

getmarks()) and adds them then displays total addition

of marks(using totalmarks()).

7. Program to obtain result of a BSc.IT student as per the ATKT pattern if

the student is having KT print number of KT and Subject Name in which

he failed.If more than 2KTs fail & If no kt pass

1. Reverse of a Number

Code:

#include

#include //For clrscr() & getch()//

void main()

{

long num, digit, rev=0;

clrscr();

cout


3/21

OUTPUT:

************************************************** *

* Program for Reverse of a Number *

* *

*************************************************

Enter the Number

154

Reverse = 451



4/21

2. Factorial of a Number

Code:

#include

#include

void main()

{

clrscr();

cout


5/21

OUTPUT:

*************************************************

* ** Program for Factorial of a Number *

* *

*************************************************

Enter the Number to find its Factorial

8

Factorial => 40320

3. Switch case to perform certain operations on a Number

Code:

#include

#include

#include //For Math functions like Sin,Cos & Pow

void main()

{

int num,sw;

float ans;

clrscr();

cout


7/21

cout


8/21

cout


9/21


10/21

OUTPUT for option 2:

Program to find Power of a number

Enter the base value2

Enter the power

4

16


Enter the number to find its Squareroot

5

Squareroot of num=2.236068


Enter the number to finds its Sin

5

Sin of number=-0.958924


Enter the number to find its Cos6

Cos of number=0.96017

OUTPUT for default option:

U ENTERED WRONG OPTION !!!!!!!!!!!

4. Palindrome of a Number

Code:

#include

#include

void main()

{

long number,num, digit, rev=0; // initialize three integer variables

clrscr();

cout


12/21

else

{

cout

5. Studying how to use class and functions in a program

Code:

#include

#include

class student //student is the name of class

{

int marks1, marks2;

public: // access specifier as public

void getmarks();

/*Declaring a Function & void specifies return type of function getmarks.*/

void totalmarks();

/*Declaring a function & void specifies return type of function totalmarks.*/

};

void student:: getmarks() /*void - return type & student - class name & :: -

scope resolution operator for getmarks*/

{

coutmarks1 >> marks2;

}

void student:: totalmarks()

{

cout


14/21

getch();

}

OUTPUT:

Enter the marks of Two Subjects

98

96

The marks for two subjects are

98 96

Total of Marks =>194

6.

#include

#include

class student

{

char name[20];

int rollno;

int marks[5];

int total;

float per;

public:

void getdata();

void getmarks();

void showdata();

void showmarks();

};

void student :: getdata(){

coutname;

coutrollno;

}

void student :: getmarks()

{

cout


16/21

void student :: showdata()

{

cout


17/21

7. Program to obtain result of a BSc.IT student as per the ATKT pattern if the

student is having KT print number of KT and Subject Name in which he failed.

If more than 2KTs fail & If no kt pass

Code:#include

#include

class student //This class contains basic info like Name and Roll no.

{

int rollno; // As it is private cannot be used outside this class

public:

char name[30]; //Name declared in array

void getdata();

void showdata();

};

void student :: getdata() //This function is used to Obtain Name and Roll no

{

coutname;

coutrollno;

}

void student :: showdata() //This function Displays Name and Roll no

{

cout


18/21

{

public:

int marks[5]; //Marksvoid getmarks();

};

void marks :: getmarks()

{

coutmarks[i];

}

}

class bonus_marks: public marks

{

public:

void bonusgrace();

void total();

void showmarks();

};

void bonus_marks :: bonusgrace()

{

for (int i=0; i


19/21

void bonus_marks :: total()

{

int total=0;

for(int i=0 ; i


20/21

++count;

}

}

if (count>0){

cout


21/21

cout
