Tic Tac Toe (need help)

[mpike]

Here's my problem my assignment is to create a tic tac toe game with classes included (public and private) with only a few functions in int main.

#include <iostream>
   
      #include <string>
   
      using namespace std;
   
       
       
       
       class cgame {
             
             private:
                     
      int iTurn; 
  
      int turns; 
  
      int gameWon; 
  
      int i;
      
      
      public: 
  
       
  
      bool validMove;
  
      bool gameQuit;
      
      public:
             
            void data()
            {
                 
                 
            int  iTurn (1);
            int  turns (0);
            int   gamesWon (0);
              
            bool      validmove(false);
            bool     gamequit(false);

      };
             
             
             
                int main () {
                    
  char cPause;                  
                    
                    
   
cgame g1;
g1.data();

 
       
 
      cout << "\n\nThanks for playing\n";
 
      cin >> cPause;

      }

when i start the program and enter then first spot to place my x or o it ends the game. but when i hit play again everything works perfectly so im guessing it has to do with the initialization but i cant figure it out help please.

Two things (maybe)

1) std::string squareArray[] = {"0","1","2","3","4","5","6","7","8","9"}; looks scary. I would use: std::string squareArray[10] = {"0","1","2","3","4","5","6","7","8","9"}; 2) It looks like you don't initialize your member variables.

Make a constructor and in it initialize iTurn, turns, gameWon, and i.

('i' doesn't seem like a good candidate to be a member variable in the first place...)

Good luck,

David
