实现 2 人游戏井字游戏(用户对用户)
原文:https://www . geesforgeks . org/implementation-of-TIC-tac-toe-for-person-game-user-vs-user/
单人游戏(用户对 CPU)请参考井字游戏的实现
游戏规则
- 游戏将在两个人之间进行(在这个程序中是人类对人类)。
- 首先，游戏将把两个玩家的名字作为输入。
- 其中一个玩家选择“O”，另一个选择“X”来标记他们各自的细胞。
- 将会有一个游戏抛硬币，决定哪个玩家先走。
- 游戏从其中一个玩家开始，当其中一个玩家有一整行/一列/一条对角线填充了他/她各自的角色(“O”或“X”)时，游戏结束。
- 如果游戏是平局，则显示消息“游戏是平局”。
获胜策略——一个有趣的事实 如果双方都打得很好，那么你注定永远不会输(“尽管比赛仍然可以平局”)。打第一还是第二不重要。换句话说——“两个高手总会打平”。 这不是很有意思吗？
下面是游戏的代码:
