Question

我需要制作一个使用1-9格的双人tic tac toe游戏。玩家输入他们想要的字母代表的数字。但是，我无法识别谁赢了。在输入的每个数字之后，它表示输入数字的最后一个玩家赢了。

#include <iostream>

using namespace std;

int main()
{

int Xp, Op, turn;
char board[9] = {'1','2','3','4','5','6','7','8','9'};

cout << "Please enter a number on the board that is the spot you wish to use" << endl;

cout << "Board:\n";

cout << board[0] << " " << board[1] << " " << board[2] << endl;
cout << board[3] << " " << board[4] << " " << board[5] << endl;
cout << board[6] << " " << board[7] << " " << board[8] << endl;

do
{
for (turn=1; turn<10; turn++)
    if (!(turn % 2) == 0)
    {
        cout << "\nPlayer X's turn." << endl;
        cin >> Xp;
        board[Xp-1] = 'X';

cout << "Current Board:\n";

cout << board[0] << " " << board[1] << " " << board[2] << endl;
cout << board[3] << " " << board[4] << " " << board[5] << endl;
cout << board[6] << " " << board[7] << " " << board[8] << endl;




if((board[0]&&board[1]&&board[2] == 'X') || (board[3]&&board[4]&&board[5] == 'X') || (board[6]&&board[7]&&board[8] == 'X') || 
 (board[0]&&board[3]&&board[6] == 'X') || (board[1]&&board[4]&&board[7] == 'X') || (board[2]&&board[5]&&board[8] == 'X') || 
 (board[0]&&board[4]&&board[8] == 'X') || (board[6]&&board[4]&&board[2] == 'X'));
 {          
   cout << "Player X wins!!!!" << endl;
 }      
    else
    {

        cout << "\nPlayer O's turn." << endl;

        cin >> Op;
        board[Op-1] = 'O';

cout << "Current Board:\n";

cout << board[0] << " " << board[1] << " " << board[2] << endl;
cout << board[3] << " " << board[4] << " " << board[5] << endl;
cout << board[6] << " " << board[7] << " " << board[8] << endl;

if((board[0]&&board[1]&&board[2] == 'O') || (board[3]&&board[4]&&board[5] == 'O') || (board[6]&&board[7]&&board[8] == 'O') || 
 (board[0]&&board[3]&&board[6] == 'O') || (board[1]&&board[4]&&board[7] == 'O') || (board[2]&&board[5]&&board[8] == 'O') || 
 (board[0]&&board[4]&&board[8] == 'O') || (board[6]&&board[4]&&board[2] == 'O'));
{           
cout << "Player O wins!!!!" << endl;
}

    }
}
while(turn<10);

cout << "We have a tie!!!";

return 0;
}

问题在于if语句如下所示：

if((board[0]&&board[1]&&board[2] == 'X') || (board[3]&&board[4]&&board[5] == 'X') || (board[6]&&board[7]&&board[8] == 'X') || 
 (board[0]&&board[3]&&board[6] == 'X') || (board[1]&&board[4]&&board[7] == 'X') || (board[2]&&board[5]&&board[8] == 'X') || 
 (board[0]&&board[4]&&board[8] == 'X') || (board[6]&&board[4]&&board[2] == 'X'));
 {          
   cout << "Player X wins!!!!" << endl;
 }

在您打算成为if语句主体的代码块之前有一个;。 ;结束语句，使下一个块不再是if的一部分，而只是一个代码块，无论条件的结果如何，都要执行。
