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.

Syntax:

Syntax to declare an array,

data_type array_name[size_declarator];

Example:

Example to declare an array,

//Declaration of an array

int values[5];

In the above example, “int” represents the data type of the array, “values” is the array name and the number inside the bracket is the size declarator of the array.

• Here, the array “values” holds “5” values.
• The array index values starts from “0” and ends with “4” to hold five elements.

Given code:

/*Array declaration of type double that is assigned to hold four values. */

double array1[4] = {1.2, 3.2 , 4.2, 5.2};

/*Array declaration of type double that can hold four values. */

double array2[4] ;
