Program Plan Intro

Array:

An array is defined as a group that consists of similar data types, but the size of array can also declared which indicates that the number of values an array can hold and it is always indexed, starting from 0.

Declaration of an array variable:

• • An array variable is declared with “[]” after the data type.
• • The following is the syntax for declaring an array variable.

dataType[] arrayVar;

   or

dataType arrayVar[];

• • Both the above given statements can be used, but the former one is mostly used.
• • The element type can be any data type and the same data type must be used by all the elements.

Use the loop to iterate an array value:

The loop helps to iterate an array value by performing the same operation on each and every element.
