Question

所以我试图编写一种方法来重播一个tic tac toe游戏后，有人获胜，失败或关系。所以基本上我试图重播工作，不起作用。如果玩家1获胜并且我输入1进行重播，则会询问玩家2他们的输入。

伪代码轮廓：

do {
  set entire 2d array to '*'
  do {
    player 1 input
    does game tie?
    does player 1 win
    player 2 input
    does game tie?
    does player 2 win
  } while no one wins
} while replay = 1

我的实际代码：

//tie check, replay, use pointer notation
#include <iostream>
using namespace std;

void initialize(char [][3]);
void player1(char [][3]);
void player2(char [][3]);
void display(char [][3]);
char check(char [3][3]);
int checkWin(int);
int tie(int);
int askReplay();
int main()
{
    char board[3][3];
    char end = '*';
    int row1, column1, row2,column2;
    int replay = 0;
    int turns = 0;
    //replay loop
    do {
        //set board to *
        initialize(board);
        display(board);
        do {
            //player 1 turn
            player1(board);
            turns++;
            display(board);

            //if turns = 9 then tie
            replay = tie(turns);
            //check if player 1 won
            end = check(board);
            replay = checkWin(end);

            //player 2 turn
            player2(board);
            turns++;
            display(board);

            //if turns = 9 then tie
            replay = tie(turns);
            //check if player 2 won
            end = check(board);
            replay = checkWin(end);

        } while (end == '*');
    } while (replay == 1);
    return 0;
}

Answer 1

听起来你的主循环遇到了麻烦。

我建议制作一个控制哪个播放器正在运行的变量，然后切换它。

do  
{    
  set entire 2d array to '*'  
  current player = 0
  do  
  {  
    (current player + 1) input  
    does game tie?  
    does (current player + 1) win

    current player = (current player + 1) % 2  
  }while no one wins     
}while replay = 1

看看是否能让你更进一步。
