Hello, trying to write program that uses a stack to print prime factors of a positive integer in descending order.

It has to run on Visual studios but every help I have gotten it only works on other IDE's. The requirements are to make it work only using VS debug. not in command prompt or anything else. I have been having difficulty figuring out how to use stack in my current code. So how would I add stack to my code and it run in visual studios?

#include <iostream>

#include <vector>

#include <stack>

using namespace std;

vector<int> factors(int n) {

   vector<int> result;

   int a = 2;

   while (a * a <= n)


      if (n % a == 0)



         n = (n / a);







   if (n > 1)


   return result;


int main()


   int x;

   cout << "Input positive integer greater than 1: ";

   cin >> x;

   vector<int> result_factors = factors(x);

   cout << "The result: ";

   for (int i : result_factors)

      cout << "i ";

   cout << endl;

   return 0;
