问题描述
我注意到当您为TicTacToe表输入错误的数字时，我的程序输出无效动作".是什么原因造成的?我只使用过一次move(row，col)方法，因此它不应重复两次Invalid Input.
I've noticed that my program outputs "Invalid move" when you put in an incorrect number for the TicTacToe table. What would cause this? I only use my move(row, col) method once so it shouldn't repeat Invalid Input twice.
我一直在构建Tic Tac Toe程序，相信我已经完成了99.9％.我无法找出一个讨厌的循环，并且我已经添加了一段时间以尝试修复它.我认为这只是我似乎无法注意到的一个小愚蠢的错误.
I've been constructing a Tic Tac Toe program and I'm 99.9% done I believe. There is one pesky loop that I cannot figure out, and I've been adding things for a while to try and fix it. I think it's just a small dumb mistake I can't seem to notice by myself.
无论如何，问题出在我完成游戏并输入Yes之后，程序终止并结束.可能是由于我将while循环放入另一个do while循环而导致的，所以我可以中断它，然后立即回到它.
Anyway the problem is once I completed a game and type Yes the program terminates and ends. What could be causing this since I put my while loop inside of another do while loop so I could break out of it and then just go back into it right away.
这是我的全部代码.

推荐答案
您的条件检查有效:
while (quitGame = false);
应为:
while (quitGame == false);
双等于号.
