Example: HARSHAD Number or Not in C using For loop

#include <stdio.h>

​

// It's the main function of the program

int main()

{

    int num, sum = 0;

​

    // Step-1 Take an input from the User

    printf("INPUT A NUMBER: ");

    scanf("%d", &num);

​

    // Step-2 Store the input value into another variable

    int original = num;

​

    // Step-3 Use a loop to check the Harshad number

    for (original != 0; original /= 10;)

        sum += original % 10;

​

    // Step-4 Compare the input value with the sum of divisors of the input value

    if (num % sum == 0)

        printf("\n%d IS A HARSHAD NUMBER\n", num);

    else

        printf("\n%d IS NOT A HARSHAD NUMBER\n", num);

​

    return 0;

}
