1. Arrays2.Introduction to object oriented programming

language. 3.several C++ enhancements to C.4. what classes, objects, member functions and

data members are.5.how destructors are used to perform

termination.


.5.housekeeping on an object before it is destroyed .

6.what operator overloading is and how it makes programs more readable and programming more convenient.

7.To create classes by inheriting from existing classes and how inheritance promotes software reuse, the use of inheritance to customize existing software.


.8. what polymorphism, how it makes

programming more convenient and how it makes systems more extensible and maintainable .

Arrays


Q: Define an array?An array is a variable that can store

multiple values of the same typeQ: Write a format for declaring a one

dimensional array?

EX: int tests[5];

<Data type> < Array Name > [ Array Size declarator] ;


Q: Design an array - Memory Layout for the following array

int tests[5];allocates the following memory:

Subscripts 0 1 2 3 4

first element

second element

third element

fourth element

fifth element


Array Terminologies Q: What is the difference between

the array size declarator and the array size ?

The array size declarator shows the number of elements in the array.

The size of an array is the total number of bytes allocated for it . It is =

(number of elements) * (number of bytes for each element)


.Q: Calculate the size of these

arrays? 1. int tests[5] is an array of 20 bytes, assuming

4 bytes for an int

2. long double measures[10]

is an array of 80 bytes, assuming 8 bytes for a long double
