Write a C Program to check even or odd number

• The program first declares a variable num to store the user input.
• It then prompts the user to enter a number using the printf() and scanf() functions.
• An if-else statement is used to check whether num is even or odd using the modulo operator %. If the remainder of num divided by 2 is equal to 0, the program prints that num is even. Otherwise, the program prints that num is odd.
• Finally, the program returns 0 to indicate successful execution.

#include <stdio.h>

int main() {
    int num;

    printf("Enter a number: ");
    scanf("%d", &num);

    if (num % 2 == 0) {
        printf("%d is even.", num);
    } else {
        printf("%d is odd.", num);
    }

    return 0;
}

OUTPUT

Enter a number: 7
7 is odd.
