Chapter 8, Problem 36RQE

A)

Program Plan Intro

Array:

An array is a data structure which stores multiple values of same types of data; the array values are stored in continuous memory locations.

• Size of an array has been declared inside a square bracket, which is named as size declarator.
• The size declarator must be declared as an integer with a value greater than “0” and the number inside the brackets represents the number of elements that the array can hold.

Structure array:

The structure needs an array if the items needs to be grouped together.

• Array is a “derived” data type and it contains similar elements.
• The array index starts with 0.
  • If the size of the array is 4, then the index values are “0”, “1”, “2”, and “3”.

Syntax:

struct_name array_name[size];

Example:

Book name[20];

Explanation:

“Book” is a structure name, “name” is an array name, and the value “20” is the “size” of an array.

Program Plan Intro

Array of Objects:

Object is an instance of the class. Objects of the class can also be given in the form of an array, in which the array values are passed into an overloaded constructor.

Syntax: classname object[size];
