C Exercises: Find Harshad Number between 1 to 100

C Numbers: Exercise-18 with Solution

Write a program in C to find Harshad Number between 1 to 100.

Sample Solution:

C Code:

# include <stdio.h>
# include <stdlib.h>
# include <stdbool.h>


bool chkHarshad(int n)
{
    int s = 0;
	int tmp;
    for (tmp=n; tmp>0; tmp /= 10)
        s += tmp % 10;
    return (n%s == 0);
}
int main()
{
    int i;
	printf("\n\n Find Harshad Numbers between 1 to 100: \n");
	printf(" ---------------------------------------------------\n");
	printf(" The Harshad Numbers are: ");
for(i=1;i<=100;i++)
{
     if( chkHarshad(i))
	printf("%d ",i);
}
	printf("\n");

}

Sample Output:

 The Harshad Numbers are: 1 2 3 4 5 6 7 8 9 10 12 18 20 21 24 27 30 36 40 42 45 48 50 54 60 63 70 72 80 81 84
 90 100
