我不确定如何从已有的内容着手：我无法让我的阵列正常工作，而且每次重新运行程序时我的图表重置也有问题。它不会保存我的 X 和 O，而是重新启动到空白图表中。任何提示都会有所帮助。谢谢
/**
Lab 4 - Due 7/22/2010.
Convert Lab 3 to a class
1. Implement displayBoard to display Tic Tac Toe board.
2. Prompt User for a box on the board to select, i.e. a number between 1 and 9 with 1 being the upper left corner.
use cin.get(box) to get the box number and isdigit to verify it is a
number;
1 | 2 | 3
4 | 5 | 6
7 | 8 | 9
If the box is available put the appropriate X or O in there and switch players, i.e. X becomes O and vice versa.
If the box is NOT available warn the user and get another box until they select a valid open box.
3. After all spots have been select Display "Game Over!";
4. Write a main function to use the TicTacToe class and test all of the above functionality.

@Bunnit 根据您的建议，我能够对其进行更改。现在我唯一的问题是用 X 或 O 替换每个框，这似乎不像我的 if 和 else if 工作。
