In this tutorial, we are looking new program which is to find an even or odd number.

In this program, we first have a number and we check whether that number is Even or odd programmatically.

### Definition of odd and even numbers

**What is even number?**

Any number which is divided by 2 and gives the remainder zero is Even number.

**What is an odd number?**

Any number which is divided by 2 but gives reminder 1 is an odd number.

To check whether a number is even or odd we need some basic mathematical formula.

The mathematical formula to find out whether a number is even or odd is as follows

**Result = Number % 2**

In above formula, The number is any number of which we are checking even or odd number.

If this number gives the reminder 0 then it’s even number else number is odd.

**Example**

Number = 10

Reminder = Number % 2

Reminder = 0

So, Number is even

Number = 5

Reminder = Number % 2

Reminder = 1

So, Number is odd.

In this way, we check whether Number is even or odd.

Using this way we implement the program to find even or odd in c.

### C Program to Check Whether the Given Number is Even or Odd

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
#include<stdio.h> Void main() { int number; printf("Enter a Number \n"); scanf("%d", &number); if(number % 2 == 0) { printf("The number %d is Even", number); } else { printf("The number %d is Odd",number); } printf("\n"); } |

**Output**

**Enter a Number**

**5**

**The number 5 is Odd**

**Explanation**

- First, Here we declared an integer number.
- Then we took the input from a user using scanf statement.
- As we know modulus operator is used to return the remainder of two values as (10%3=1, 12%2=0).
- So if you do modulus with 2 then the remainder would be ‘zero’ for Even numbers and ‘1’ for Odd numbers.
- If we divide ‘number’ with ‘2’ using mod operator then depending upon condition the respective ‘printf’ will be executed.
- In above output, 5 % 2 = 1 so The number is odd will be printed.
