I am getting no errors but no out put for my program??

Question

#include <iostream>

using namespace std;

int
main ()
{
  int x, a, b, sum, diff, product, divison;
  cout << "enter a no.\n";
  cin >> a;
  cout << "enter another no. \n";
  cin >> b;
  cout << "enter the operator\n";
  cin >> x;

  if (x == sum)
    {
      sum = a + b;
      cout << "sum=" << sum << endl;
    }
  else if (x == diff)
    {
      diff = a - b;
      cout << "diff=" << diff << endl;

    }
  else if (x == product)
    {
      product = a * b;
      cout << "product=" << product << endl;

    }
  else if (x == divison)
    {
      divison = a / b;
      cout << "divison=" << divison << endl;
    }
  return 0;
}

when I ran this program online it gave the accurate result.... but when I tried running this program on my computer I get no output just three entries but no result

Answer 1

change the sum,diff,product,division with the number because the x is an integer variable it cannot store alphabets
