井字游戏编程帮助 C++

Question

我的主要问题是，如何让标记（X 和 O）出现在游戏板上？我必须向用户询问行号和列号，然后令牌就会放在那里。您可能会说，我是编程新手。我已经在这几个小时了，我只是想完成。在这里问是我最后的手段。如果任何代码可以以不同的方式或更有效地完成，或者没有必要，或者我做错了什么，请告诉我。我没主意了。我只是想完成这个程序，所以你越详细越好。我非常感激。我很困惑，真的需要建议来完成这个。

到目前为止我的代码：

#include <iostream>
using namespace std;

void createBoard(int board[][3], char charBoard[][3]);
void printBoard(char charBoard[][3]);
int checkWinner (int board[][3], int player);
bool checkMove(int board[][3], int row, int column);
void resetBoard(int board[][3]);

int main ()
{
    int board[3][3];
    char charBoard[3][3];
    int player;
    int row, column;
    bool win = false;
    char again = 'y';

    while (win == false)
    {
        createBoard(board, charBoard);
        printBoard(charBoard);
        cout << "Player O's turn!" << endl;
        cout << "Enter row number: "; cin >> row;
        cout << "Enter column number: "; cin >> column;
        checkMove(board, row, column);
        //update board
        win = checkWinner(board, -1);
        if (checkWinner (board, -1)  == true)
        {
            cout << "Player O wins!" << endl;
            break;
        }
        //set flag to denote it's x's turn
        printBoard(charBoard);
        cout << "Player X's turn!" << endl;
        cout << "Enter row number: "; cin >> row;
        cout << "Enter column number: "; cin >> column;
        checkMove(board, row, column);
        //update board
        win = checkWinner (board, 1);
        if (checkWinner (board, 1) == true)
        {
            cout << "Player X wins!" << endl;
            break;
        }


        cout << endl << endl;
        cout << "Would you like to play again? (y/n): ";
        cin >> again;

        }
        cout << endl << endl;
        cout << "Good bye!" << endl;

        return 0;
}



void createBoard(int board[][3], char charBoard[][3])

            if (board[i][j]== -1)
            {
                charBoard[i][j] = 'O';
            }
            // if game board has a 1, put an "X" in the character board
            else if (board[i][j]== 1)

Answer 1

看起来您应该在“checkMove”函数中插入适当的值：

else if (board[row][column] == 0)
{
    board[row][column] = value;    // value -1 or 1
    return true;
}

“值”是 -1 或 1，具体取决于您插入的是 X 还是 O。函数本身没有任何关于谁添加标记的信息，因此您可以添加另一个参数传入“值”的函数。
