Thread: program exits when it isn't supposed to

Hey all,

I'm (still) working on my console-based chess program. I have most of it worked out, but I've run across a problem:

after a few turns, it just exits. (says "Press enter to continue...")

This is weird because the program is just an infinite loop (for(;) with no way for the program to actually exit (I'm lazy and havn't put in a "Quit?" thing yet).

Here is the main cpp file:

Code:

// chess, main program
// last updated 10-24-02
// Will Herrick

#include <iostream>
#include "board.h"

using namespace std;

int main()
{
	int a;
	int b;
	int c;
	int d;
	int turn;
  bool valid;
  bool check;
	
	BOARD board;
	board.showBoard();
	board.setTurn(1); // set white first
	
	for(;;)
	{
		turn = board.getTurn();
		
		if(turn == 1) cout << "Whites turn, ";
		else if(turn == 2) cout << "Blacks turn, ";
		
		cout << "Make your move:" << endl;
		cin >> a >> b >> c >> d;
		
		valid = board.Move(a,b,c,d);
		
  		if(valid == false)
    			cout << "Invalid move" << endl;
  		if(valid == true)
  		{
  			board.showBoard();
  			if(turn == 1) board.setTurn(2);
  			if(turn == 2) board.setTurn(1);
    			check = board.isCheck();
    			if(check == true)
    			{
      				cout << "Check!";
      	  }
		  }
  	}
	return 0;
}

I'm not posting the other bits (board .cpp) because they are long, but I can do so if necessary.

What might be a reason for this oddity?

Thanks!

Try running it through a debugger?

Debuggers are for weaklings!

Just kidding

I guess that would be a good idea actually... but I'm going to have to learn how to use gdb in KDevelop :-/
