Question

Yeah. So, I’m trying to make a code for a guessing game. In this game, there’s a hard mode. In hard mode, you have 15 guesses, and have to guess between 1 and 500. But my problem is this:
I’m trying to have hard mode save & display your wins/losses, but when it outputs the contents of wins.txt it outputs something like this:

Wins: 0x7fffee26df78
Losses: 0x7fffee26e178

It’s really confusing me. Here’s the part of the code I have for that:

ifstream losses_var("losses.txt");
ifstream wins_var("wins.txt");
losses_var>> loss;
wins_var>> win;
wins_var.close();
losses_var.close();

Then it gets called with:

cout<<"Wins: "<< wins <<"\nLosses: "<< losses <<"\n"

If you would like to see the full source code, it’s here: http://pastebin.com/gPT37uBJ

My second problem:
Hard mode won’t display when you win. That’s pretty much the whole problem. In my code, the loop for asking users for input uses
while (guess != randNum)
So at the end bracket I have what I want the code to display when a user wins, but it just doesn’t run. It just stops. I would like it if someone could help me with this. The line that has the bug is line 97 through 105. Again, source code is here: http://pastebin.com/gPT37uBJ

Answer 1

Others have already answered the output problem (win vs. wins). The other problem is probably in your logic of while loop nesting. The outer loop (while (guess != randNum)) starts, but its body contains the entire inner loop (while (guesses_left != 0)). This means that the outer condition is not checked again until the inner loop terminates, which means you’ve run out of guesses. Also note that if you guess correctly, inner loop will never terminate. You probably want something like this:

while (guesses_left > 0) {
  // input user's guess
  if (guess < randNum) {
    // process it
  } else if (guess > randNum) {
    // process it
  } else {
    // it's equal, user won
    // do what's necessary for a win
    return 0;
  }
}
// ran out of guesses
// do what's necessary for a loss
return 0;
