Check if the sum of digits of a number N divides it
Given a number N. The task is to check if the sum of digits of the given number divides the number or not. If it divides it then print YES otherwise print NO.
Examples:
Input : N = 12 Output : YES Sum of digits = 1+2 =3 and 3 divides 12. So, print YES. Input : N = 15 Output : NO
Extract digits of the number and calculate the sum of all of its digits and check if the sum of digits dives N or not.
Below is the implementation of the above approach:
C++
// C++ program to check if sum of // digits of a number divides it #include <iostream> using namespace std; // Function to check if sum of // digits of a number divides it int isSumDivides(int N) { int temp = N; int sum = 0; // Calculate sum of all of digits of N while (temp) { sum += temp % 10; temp /= 10; } if (N % sum == 0) return 1; else return 0; } // Driver Code int main() { int N = 12; if (isSumDivides(N)) cout << "YES"; else cout << "NO"; return 0; } |
