Can anyone explain how this c++ code works?

Question

C++ / C#

Here is the code itself:

#include <iostream>

using namespace std;

int main() {

  int n;

  int s;

  n = 0;

  s = 0;

  while (s <= 257) {
    s = s + 10;
    n = n + 3;
  }

  cout << n <<endl;
  system("pause");
  return 0;
}

How does this cycle work?

Answer 1

And what exactly is unclear here? It says to loop while s is less than or equal to 257 .
