Even or odd

1. Odd or even program in C using modulus operator

#include <stdio.h>

int main()
{
  int n;

  printf("Enter an integer\n");
  scanf("%d", &n);

  if (n%2 == 0)
    printf("Even\n");
  else
    printf("Odd\n");

  return 0;
}

2.C program to find odd or even using bitwise operator

#include <stdio.h>

int main()
{
  int n;
 
  printf("Input an integer\n");
  scanf("%d", &n);

  if (n & 1 == 1)
    printf("Odd\n");
  else
    printf("Even\n");
 
  return 0;
}

3. C program to check odd or even without using bitwise or modulus operator

#include <stdio.h>

int main()
{
  int n;

  printf("Enter an integer\n");
  scanf("%d", &n);

  if ((n/2)*2 == n)
    printf("Even\n");
  else
    printf("Odd\n");

  return 0;
}

4. C program to check even or odd using conditional operator

#include <stdio.h>

int main()
{
  int n;

  printf("Input an integer\n");
  scanf("%d", &n);

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

  return 0;
}
