# Divisors of n-square that are not divisors of n in C++ Program

In this tutorial, we are going to write a program that finds the divisors count of n-square and not n.

It's a straightforward problem. Let's see the steps to solve the problem.

• Initialize the number n.

• Initialize a counter for divisors.

• Iterate from 2 to n^2n2﻿.

• If the n^2n2﻿ is divisible by the current number and nn﻿ is not divisible by the current number, then increment the count.

• Print the count.

## Example

Let's see the code.

Live Demo

#include <bits/stdc++.h>
using namespace std;
int getNumberOfDivisors(int n) {
int n_square = n * n;
int divisors_count = 0;
for (int i = 2; i <= n_square; i++) {
if (n_square % i == 0 && n % i != 0) {
divisors_count++;
}
}
return divisors_count;
}
int main() {
int n = 6;
cout << getNumberOfDivisors(n) << endl;
return 0;
}

## Output

If you execute the above program, then you will get the following result.
