C++ Exercises: Find Harshad Number between 1 to 100

C++ Numbers: Exercise-21 with Solution

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

Sample Solution:

C++ Code :

#include<bits/stdc++.h>
using namespace std;
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;
 cout << "\n\n Find Harshad Numbers between 1 to 100: \n";
 cout << " ---------------------------------------------------\n";
 cout << " The Harshad Numbers are: "<<endl;
for(i=1;i<=100;i++)
{
     if( chkHarshad(i))
        cout << i<<" ";
}
        cout << endl;

}

Sample Output:

 Find Harshad Numbers between 1 to 100:                                                              
 ---------------------------------------------------                                                 
 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
