Question

Write a C++ program that displays the numbers between 1000 and 9999, which are divisible by sum of the digits in them. For example, 2924 is divisible by (2+9+2+4 = 17). Your program should display all these possible numbers in the given range, and each number should be separated from the other by a space.

Answer 1

According to the problem statement above,

I have coded the function using C++

Code in Text format:

#include <iostream>
using namespace std;

int main()                                     // main starts from here
{
  
    for(int i = 1001; i<9999; i++)               // loop starts from here
    {
        int n = i, sum = 0, m;                   // variables to achieve logic
      
        while(n > 0)                           // inner loop to find sum of digits of i
        {  
            m = n % 10;  
            sum = sum + m;  
            n = n / 10;  
        }
        if(i % sum == 0)                       // if sum is divisible by i
        {
            cout << i << " ";                   // printing i         
        }
    }
    return 0;
}

I hope the above snippets, information, and the explanation will help you out!
