## Logic to check even or odd

A number exactly divisible by 2 leaving no remainder, is known as even number. Programmatically, if any number modulo divided by 2 equals to 0 then, the number is even otherwise odd.

Step by step descriptive logic to check whether a number is even or odd.

1. Input a number from user. Store it in some variable say num.
2. Check if number modulo division equal to 0 or not i.e. `if(num % 2 == 0)` then the number is even otherwise odd.

Important Note: Do not confuse modulo division operator `%` as percentage operator. There is no percentage operator in C.

Let us write program to check even odd.

## Program to check even or odd

``````/**
* C program to check even or odd number
*/

#include <stdio.h>

int main()
{
int num;

/* Input number from user */
printf("Enter any number to check even or odd: ");
scanf("%d", &num);

/* Check if the number is divisible by 2 then it is even */
if(num % 2 == 0)
{
/* num % 2 is 0 */
printf("Number is Even.");
}
else
{
/* num % 2 is 1 */
printf("Number is Odd.");
}

return 0;
}``````

Output

```Enter any number to check even or odd: 11
Number is Odd```
