A program to check odd and even number.

#include<stdio.h>;
void main()
{
    int number;
    printf("Enter a number :");
    scanf("%d",&number);
    if ( number%2 == 0 )
        printf("n Entered number is even n");
    else
        printf("n Entered number is odd  n");
}

NOTE : You can see we use == in if this is equal operator if we use it once (ex: number=50) it

assigned the value 50 to number but if we use == it compare the value of number with 50.

OUTPUT : 1.

Enter a number : 50
Entered number is even

2.

Enter a number : 5
Entered number is odd
