Random chance

[PantelisF]

Hi there, i started learning C++ 3 days ago and i am really excited.I wrote this small code and i wanna know if there is a way to Declare a certain value for the abortion chance?

#include <iostream>

using namespace std;

int random(int);

int main ()
{
  srand(time(0));
  int n,max,o,chance;
  cout << "Put a random number:\n";
  cin >> max;
  o=random(max);
  for (max=max; max>0; max--)
  {
    cout << max << ", ";
    if (max==random(o))
    {
      cout << "Something evil aborted the countdown\n\a";
      break;
    }
  }
  return 0;
}
int random(int o) {
  return rand()%o;
  
}

What do you mean? Your code doesn't even use those variables, i mean 'chance' or 'n'. What are they for??
