C Program to Check Odd or Even

by

How to write a C Program to Check Odd or Even number 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 checks whether that number is even or odd 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 number.

/* C Program to Check Odd or Even using IF Condition */

#include<stdio.h>

int main()
{
  int number;

  printf(" Enter an int value to check Even or Odd \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;
}

ANALYSIS

Within this C Odd or Even example, below printf statement will ask the user to Enter a value to check whether it is Even or Odd.

printf(" Enter an int value to check Even or Odd \n ");

Below scanf statement will assign the user entered a value to a number variable.

scanf(" %d ",&number);

In the Next line, We declared the If statement

if ( number % 2 == 0 )

Any number that is completely divisible 2 is even number. If condition check whether the remainder of the number divided by 2 is exactly equal to 0 or not.

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

OUTPUT

C Program to Check Odd or Even 1 odd

Enter the second value to check for the even number

C Program to Check Odd or Even 1 even

You can observe from the above c odd or even code that 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 is even or odd in c programming. Let’s see the example of this

/* C Program to Check Even or Odd Using Conditional Operator */
#include<stdio.h>

int main()
 {
  int number;

  printf(" Enter an int value to check Even or Odd \n ");
  scanf("%d",&number);

  number%2 == 0 ? printf(" Even Number \n ") : printf(" Odd Number \n");

  return 0;
 }

OUTPUT

C Program to Check Odd or Even 2
