How to Write a C Program to Check Odd or Even numbers using If Statement and Conditional Operator with an Example of Each? If a number is divisible by 2, it is an even number, and the remaining (not divisible by 2) are odd numbers.

## C Program to Check Odd or Even using IF Condition

This program allows the user to enter an integer. Next, this C program shows how to find or check even and odd numbers using the If statement.

In C Programming, we have an Arithmetic Operator called % (Module) to check the remainder of the division. Let’s use this operator to find the remainder. If the remainder is 0, then the number is even else odd.

Within this C example, the printf statement will ask the user to Enter a value to check whether it is Even or Odd. The scanf statement will assign the user entered value to a number variable.

In the Next line, We declared the If statement. Please refer to the Arithmetic Operator in C Programming article. If condition checks whether the remainder of the number divided by 2 is exactly equal to 0 or not.

- If the condition is True, it is an Even number.
- If the condition is False, it is Odd.

// using If Else #include<stdio.h> int main() { int number; printf(" Enter an int value to check \n"); scanf("%d", &number); if ( number%2 == 0 ) //Check whether remainder is 0 or not printf("Given number %d is EVEN NUMBER \n", number); else printf("Given number %d is ODD NUMBER \n", number); return 0; }

Enter the second value to check for the even number

```
Enter an int value to check Even or Odd
98
Given number 98 is EVEN NUMBER
```

In the above code, we used if condition to check whether the remainder of the given integer is 0 or not and print as per the result.

## C Program to Check Even or Odd using Conditional Operator

We can also use the Conditional operator to check whether the number 24 is odd or even in this C programming. Let’s see the example program of this.

// using Conditional Operator #include<stdio.h> int main() { int number; printf(" Enter an int value to check \n "); scanf("%d",&number); number%2 == 0 ? printf(" Even \n ") : printf(" Odd \n"); return 0; }

output

Try other values too

```
Enter an int value to check
19
Odd
```
