Even and Odd Numbers

We will write a C program to display the given numbers is even or odd and the number will be entered by the user. This will help to understand the basic structure of programming. In this program , we will display the given numbers is even or odd easily by using proper syntax and algorithms.

Program for Even and Odd Numbers

Working of Program :

In the program, we will require some numbers from the user to display that given numbers is even or odd.

Important Note :

  • If the number is completely divided by 2, then the number will be an even number.
  • If the number is not completely divisible by 2, then the number will be an odd number.

Problem 1

Write a program to check whether the number is even or odd.

  • Firstly, we have to enter the any number.
  • Then print the number.

Code

Run 
#include<stdio.h>
int main ()
{
  int num;
  printf ("Enter the number = ");
  scanf ("%d", &num);
  if (num % 2 == 0)
    printf ("%d is an even number.", num);
  else
    printf ("%d is an odd number.", num);
  return 0;
}

Output

Enter the number = 45

  • Firstly, we have to enter the any number.
  • Then print the number.

Code

Run 
#include<stdio.h>
int main()
{
    int n;
    printf("Enter the number: ");
    scanf("%d", &n);
    if (n % 2 == 0) {
        printf("The given number is EVEN.");
    }
    else {
        printf("The given number is ODD.");
    }
    return 0;
