I'm writing a program that will eventually be a Tic-Tac-Toe game, but as for now, I just want to get the layout done. Right now, all it does is read the game board from a file, display it, and then ask you where you want to save it afterwards. I'm just having a couple problems though.
When reading in a file, the format is as follows. There is exactly one space in between each symbol. The "X" symbolizes that played 'X' has taken the spot, the "O" symbolizes that played 'O' has taken the spot. A period represents an empty space:
X O .
. . .
. X .In the display function, the game board is then displayed to the screen with player positions X and O which were read from the file, but periods are now left as blank spaces.
Here is my code so far. What is wrong?!
#include <iostream>
#include <cstdlib>
#include <fstream>
using namespace std;
void readFile(char ticTacBoard[][9]);
void writeFile(char ticTacBoard[][9]);
void display(char ticTacBoard[][9]);

display(ticTacBoard);
writeFile(ticTacBoard);
