One Dimensional Array
One Dimensional Array
Size of array defines the number of elements in an array. Each element of array can be accessed and used by user according to the need of program.

Initialization One Dimensional Array
Arrays can be initialized at declaration time in this source code as
| Syntax |
|---|
| int age[5] = {2,4,6,8,9} |
Note: In do while loop the body will execute at least once irrespective of test condition.
Multi Dimensional Array
Multi Dimensional Array
The simplest form of multi dimensional array is a 2-dimensional array. It is also known as matrix. To declare multi dimensional integer array of size [x][y]. which means x is number of rows, y is number of columns can be shown in fig.

|
int c[2][3] = {{2,4},{6,8,9}}
