Wap - Even Odd Program in C

• An even number is a number that is exactly divisible by 2 and generates a remainder of 0. 
• Example: 2, 4, 6.
• Whereas an odd number is a number that is not exactly divided by 2 and generates a remainder of 1.
• Example: 1, 3, 5.

Program Description: even or Odd program in C using the modulus operator

    #include <stdio.h>
    int main() {
        int number;
        printf("Enter an integer number: ");
        scanf("%d", &number);
        //Check if number is perfectly divisible by 2
        if(number % 2 == 0){
            printf("Even Number");
        }else{
            printf("Odd Number");
        }
        return 0;
    }

OUTPUT

         Enter an integer number: 6
         Even Number

In this program, the user entered a number is stored in the variable number. If the input number is perfectly divisible, then it is even number. Else it is an odd number.    

In this program, we have used the ternary operator instead of an if-else condition.

    #include 
    int main() {
        int number, check_even;
        printf("Enter an integer number: ");
        scanf("%d", &number);
        
        check_even=(number % 2 == 0) ? 1 : 0;
        if(check_even==1){
            printf("Even Number");
        }else{
            printf("Odd Number");
        }
        return 0;
    }

OUTPUT
   
    Enter an integer number: 8
    Even Number   

Program Description: C program to find odd or even using a bitwise operator.

    #include <stdio.h>
    int main()
    {
      int number;
      printf("\nEnter an integer Number:");
      scanf("%d", &number);

      if (number & 1 == 1){
          printf("Odd Number");
      }else{
          printf("Even Number");
      }
      return 0;
    }

OUTPUT

         Enter an integer Number:6
         Even Number    

    #include <stdio.h>
    void main()
    {
        int number, rem;
     
        printf("Enter an integer Number: ");
        scanf("%d", &number);
        rem = number % 2;
        if (rem == 0)
            printf("%d is an even number", number);
        else
            printf("%d is an odd number\n", number);
    }

OUTPUT

        Enter an integer Number: 5
        5 is an odd number
