前言
检验学习成果最好的方式是实践,在学习完C语言的函数和数组以后,就可以简易的实现一些小游戏,本文将介绍如何实现三字棋小游戏。欢迎探讨
思路分析
三子棋的规则是在3X3的棋盘里,率先将自己的三个棋子连成一条直线为赢家,程序实现的核心是玩家的落子以及输赢的判断。
核心流图:当前棋盘->玩家1移动->当前棋盘->输赢判断->玩家2移动->当前棋盘->判断输赢->玩家1移动······
函数实现
玩家落子
玩家输入坐标将棋子落入棋盘中,即为向一个二维数组赋值。需要注意的时,输入的坐标不能超出数组范围,并且不能占用被输入的位置。

当前棋盘
实质是输出二维数组
输出二维数组,但是为了美化棋盘,我们需要一些符号来分割棋盘,让它结构清晰。

void DisplayBoard( char board[ROW][COL], int row, int col) { int i = 0; for (i = 0; i < row; i++) { int j = 0; for (j = 0; j < col; j++) { printf ( " %c " , board[i][j]); if (j < col - 1) printf ( "|" ); } printf ( "\n" ); if (i < row - 1) { for (j = 0; j < col; j++) { printf ( "---" ); if (j < col - 1) printf ( "|" ); } } printf ( "\n" ); } } |
判断输赢
只要我们找到三个连成一条直线的棋子即可,这里选三个棋子中中间那个即可。然后判断是不是满足条件。
说明:
返回*,表示输入*的玩家赢;
返回#,表示输入#的玩家赢;
返回 Q,表示平局;
返回C,表示游戏继续。
