what is array

In the previous post we learn about Difference between compiler and interpreter .In this post we will learn what is array.

What is array:

1. Array is used to store more than one values of same data type under a single variable name in continuous memory location.
2. In array each value has a unique index number.
3. values are start from zero(0).
4. first value will be stored at index number zero.
5. The address of first index value is also called as based address.
6. To access value in array we have to write array name followed by index number in the bracket.
7. If we don't write index number then by default first element value will be zero is accessed.

Syntax: Data type Array name [size of array];

program for print array elements:

#include <stdio.h>

void main()
{
int a[5]={2,4,6,8,10},b;
for(b=0;b<5;b++)
printf("\n%d",b[a]);
}

Output:

2
4
6
8
10

In the next post we will learn about one dimensional array and two dimensional array.
