Answer 1

#include <iostream>

int main() {
    int n = 171;  
    int reminder = 0, sum = 0;
 
    int temp = n;  
       
    while (temp > 0) {  
        reminder = temp % 10;  
        sum = sum + reminder;  
        temp = temp / 10;  
    }  
     
    // 1 + 7 + 1 = 9 : 171 % 9 = 0 <- harshad   
    if (n % sum == 0)  
        std::cout << n << " is a harshad number";  
    else 
        std::cout << n << " is not a harshad number";  
    
    return 0;  
}
