15 – C Program to check if a number is even or odd

C program to check if a number is even or odd

In programming it is easy to find if number is even or odd.

we need to divide it by 2 and if the reminder 0 then it’s even else it’s odd

In C programming we have two methods:

  1. With IF-ELSE
  2. With ternary operator

Logic to check if a number is even or odd in C

With IF-ELSE

#include<stdio.h>
//itvoyagers.in
int main()
{
int x;
printf("Enter any number : ");
scanf("%d",&x);
if(x % 2 == 0)
{
printf("n %d is Even",x);
}
else
{
printf("n %d is Odd",x);
}
return 0;
}

 

Output :

Enter any number : -9

-9 is Odd

 

Enter any number : 8

8 is Odd

With Ternary operator

#include<stdio.h>
//itvoyagers.in
int main()
{
    int x;
    printf("Enter any number : ");
    scanf("%d",&x);
    (x % 2 == 0)? printf("n %d is Even",x) : printf("n %d is Odd",x);
    return 0;
}

Output :

Enter any number : 7

7 is Odd

 

Enter any number : 8

8 is Odd
