【问题描述】：
我对编码比较陌生，我的任务是用 C++ 创建一个井字游戏，我以为我已经完成了所有代码，但是存在各种问题，例如不允许用户输入，只允许输入一个玩家的名字而不是两个，如果你能给我关于如何完成这项工作的任何帮助/建议，我们将不胜感激。
#include <iostream>
using namespace std;
int menumain;

char square8('8');

void toggleplayers() {
if (oneplayer == 'X')
oneplayer = 'O';
else
oneplayer = 'X';
}

【问题讨论】：
-
'不允许用户输入'？是否允许，就看你自己了
-
您可以通过对板子使用二维数组来简化和缩短代码。
-
按照您编写代码的方式，您很幸运井字游戏只是一个 3 x 3 的棋盘。如果它是 10 x 10，你的代码会是什么样子？识别代码中的模式，看看是否有一种概括的方法——二维矩阵的建议只是缩短代码的一步。
-
我的建议是使用 调试器 来帮助分别执行每条语句。继续执行时查看变量的值。
-
为什么要将字符分配给整数。我建议您选择不同的课程或将书扔进垃圾桶。
char类型用于字符（字母）。
