Program even and odd

Program 

 #include <stdio.h>

int main() {

    int num;

    // Input from user

    printf("Enter a number: ");

    scanf("%d", &num);

    // Check even or odd

    if (num % 2 == 0) {

        printf("The number is Even");

    } else {

        printf("The number is Odd");

    }

    return 0;

}

Explain 

• % is the modulus operator (gives remainder).
• If num % 2 == 0 → number is even
• Otherwise → number is odd

If you want, I can also show:

• Program using loop (multiple numbers)
• Program without using % operator
