old game I wrote. This was probably the first or second game I wrote using random numbers and enumerated types. The computer picks a number, and you try to guess it. Very basic and simple, but it was a beginner project. Now, looking back, I could think of a million ways to rewrite this game, with 100 more features and far more memory efficient. This is just an example code, all in all. So, if you find bugs, don't post them, as I have no intention of fixing them. I'll post better games, and codes soon enough. More games will be posted at my forum.

#include <iostream>
#include <cstdlib>
#include <time.h>

using std::cout;
using std::cin;

int main()
{
  enum difficulty {EASY = 10, NORMAL = 100, HARD = 1000};
  difficulty diff = NORMAL;

  int uDiff, pGuess, pGuesses = 0;

  cout << "Welcome to Guess My Number!\n";
  cout << "Enter 0 at any time to quit\n";

  cout << "Enter the difficulty (1-3): ";
  cin >> uDiff;
  if (uDiff == 0) { cout << "Thanks for playing! Goodbye."; return 0; }
  switch (uDiff)
  {
    case 1:
      diff = EASY;
      break;
    case 2:
      diff = NORMAL;
      break;
    case 3:
      diff = HARD;
      break;
    default:
      do {
      cout << "Invalid difficulty!\n";
      cout << "Enter the difficulty (1-3): ";
      cin >> uDiff;
      }
      while (uDiff > 4);
