How do you declare an array in a class?

Hi, I'm creating a Tic Tac Toe game and the problem I have so far is that I cant find out how to declare my array for the board in my class =( Here is my code so far. I am getting an error saying that 'Board isnt declared in this scope' so could somebody please help me with declaring Board within my class?

Code:

---

#include <iostream>
#include <string>

using namespace std;

class PlayerClass{
    public: //public consists of functions within the playerclass


    //initilises the board at the start of the game to be all 0
  void initialBoard(){
    int Board[3][3] = {{0,0,0},{0,0,0},{0,0,0}};
    for(int row = 0; row < 3; row++){
        cout<<"                    ";
    for(int column = 0; column < 3; column++){
    cout<<Board[row][column]<< " ";}
    cout<<endl;}}


    //prints out the board to show changed when a player move has made
    void printBoard(int Board[3][3]){
    for(int row = 0; row < 3; row++){
        cout<<"                    ";
    for(int column = 0; column<3;column++){
    cout<<Board[row][column]<< " ";}
    cout<<endl;}}



    //function to ask the player where they wish to place their shape and sets it to the board
    void PlayerTurn(int turn){
        if (turn == 1){cout<<"which position do you want to place your letter"<<endl;
        cout<<"enter in x coordinate";
        cin>>x;
        if(x<1||x>3){cout<<"please enter number between 1 and 3";
        cin>>x;}
        cout<<"enter in y coordinate";
        cin>>y;
        if (y<1||y>3){cout<<"please enter in a valid coordinate between 1 and 3";
        cin>>y;}
        else
        Board[x][y]=player1;
        }

        else
        if (turn == 2){cout<<"which position do you want to place your letter"<<endl;
        cout<<"enter in x coordinate";
        cin>>x;
        if(x<1||x>3){cout<<"please enter number between 1 and 3";
        cin>>x;}
        cout<<"enter in y coordinate";
        cin>>y;
        if (y<1||y>3){cout<<"please enter in a valid coordinate between 1 and 3";
        cin>>y;}
        else
        Board[x][y]=player2;}}



      private: //private consists of variables used by the functions playerclass
        char move;
        int x;
        int y;
        int turn;
        char player1;
        char player2;
                };





int main()
{
int Board[3][3] = {{0,0,0},{0,0,0},{0,0,0}};

PlayerClass Pmove;
cout<<"                Tic-Tac-Toe"<<endl<<endl;

Pmove.initialBoard();

Pmove.PlayerTurn(1);
Pmove.printBoard(Board); //needs to print the board to show where player has moved
Pmove.PlayerTurn(2);
    return 0;
}

Thanks so much =)

Similiar to how you would declare an array outside of a class, except that it would be declared as a member (like your other member variables) and you cannot initialise the array in the declaration.

In your class definition you declare board local to the constructor, you also declare an array named 'board' in your main (), this is a way to do it.

Code:

---

class MyGame
{
  public:
  int board[3][3];
 
  void InitBoard();
 
  MyGame();
};

MyGame::MyGame()
{
    //stuff...
    //..stuff...
    InitBoard();
}

void MyGame::InitBoard()
{
    for(int i = 0; i < 3; i++)
    {
        for(int j = 0; j < 3; j++)
        {
            board[i][j] = 0;
        }
    }
}

int main()
{
    MyGame game;
   
    game.board[0][0] = 1; //for example access...
}

---

In this special case of initialising to 0, you can use the initialisation list for value initialisation instead of calling InitBoard, e.g.,

Code:

---

MyGame::MyGame() : board()
{
    //stuff...
    //..stuff...
}

The indentation is horrible and unreadable. You should learn from rogster001, whose indentation is very clean and nice.

Sorry lol I use the compiler Codeblocks and if my indentation is horrible blame it on the compiler and not me! I cant be bothered to press tab every time I create a new line..

Thanks for eveybodys help, I will hopfuly be able to get this array thing working =D

I use code blocks too...the indentation is nothing to do with the 'compiler'..! Am sure you meant 'editor' but still thats not to blame..unless you have chosen a setting 'de-indent' my code!

It is a poor workman who blames his tools for his problems.

Then you can't be bothered to become a programmer.
