I tried my best and this is what I have so far, please help me out. This is my code that I need to complete.

Implement displayBoard to display Tic Tac Toe board.
Prompt User for a box on the board to select, i.e. a number between 1 and 9 with 1 being the upper left corner.

use cin.get(box) to get the box number and isdigit to verify it is a number; 1 | 2 | 3 4 | 5 | 6 7 | 8 | 9 If the box is available put the appropriate X or O in there and switch players, i.e. X becomes O and vice versa. If the box is NOT available warn the user and get another box until they select a valid open box.
After all spots have been select Display "Game Over!";

Write a main function to use the TicTacToe class and test all of the above functionality.

#include <iostream>
using namespace std;


class TicTacToe {
public:
void displayBoard();
void getMove();
void playGame();
private:
char board[9];
char player; // Switch after each move.
};

int main ()
{
TicTacToe ttt;

// you need to do the following in a loop 9 times
ttt.playGame();
}

void TicTacToe::playGame()
{
getMove();
// Your implementation here...
}

void TicTacToe::displayBoard()
{
// Your implementation here...
}

void TicTacToe::getMove()
{
cout << "Enter Box: ";
char c;
cin.get(c);
if (c > '9' || c < '0')
    // Error message here.

int number = c - '0';

cout << "your number is " << number;
// Your implementation here...
}

This is what I have so far.

#include <iostream> 

using namespace std;

void displayBoard() ;

回答1:

I'm assuming this is an assignment or homework problem?

Notice that it's asking you to fill in the implementation of some empty methods. So you need to work the code you've written into the framework of the first listing. Note also that the TicTacToe class in that listing defines the board with a array of char.

So, for example:

void TicTacToe::displayBoard(){
    std::cout << board[1] << "|" << board[2]<< "|" << board[3]<< std::endl;
    std::cout << "-+-+-"<< std::endl;
    std::cout << board[4] << "|" << board[5]<< "|" << board[6]<< std::endl;
    std::cout << "-+-+-"<< std::endl;
    std::cout << board[7] << "|" << board[8]<< "|" << board[9]<< std::endl;
}
