我们今天讲一个小游戏，三子棋大家应该都玩过吧，就是行和列，或者对角线上有一样大的字符时，就为获胜，今天我们就来写这样的一个代码实现这样的功能
首先我们要创建两个源文件和一个头文件
头文件game.h用来包含我们的头文件和函数的声明以及一些定义
game.c来实现游戏
test.c用来测试我们游戏的逻辑
test.c
#include<stdio.h>
void menu()
{printf("***************\n");printf("****0.exit*****\n");printf("****1.play*****\n");printf("***************\n");
}
void test()
{int input = 0;do{menu();//打印菜单printf("请选择>");scanf("%d", &input);switch(input){case 0:printf("退出游戏\n");break;case 1:printf("进入游戏\n");break;default:printf("请重新选择\n");break;}} while (input);
}
int main()
{test();return 0;
}
我们先实现一个打印菜单的逻辑
选择1进入游戏，选择0退出游戏，选择其他重新选择
用do while函数的话一上来就打印菜单，满足我们的需求
现在我们要实现游戏选择1完成
下一步我们要创建game（）函数来实现三子棋的逻辑
首先我们要初始化棋盘
test.c
void game()
{//存放下棋的数据char board[Row][Col ] = { 0 };//初始化棋盘为空格Initboard(board, Row, Col);
}
game.h
//初始化棋盘
void Initboard(char board[Row][Col], int row, int col);
game.c
void Initboard(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++){board[i][j] = ' ';}}}
初始化棋盘之后我们要打印棋盘，打印棋盘是个井字
game.h
//打印棋盘
void Displayboard(char board[Row][Col], int row, int col);game.c
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");}}
}
test.c
//打印棋盘Displayboard(board, Row, Col);
接下来我们要做的就是我们下棋
game.h
//玩家下棋
void play_move(char board[Row][Col], int row, int col);
game.c
void play_move(char board[Row][Col], int row, int col)
{int x = 0;int y = 0;printf("玩家下棋\n");while (1){printf("请输入坐标>");scanf("%d %d", &x, &y);if (x >= 1 && x <= row && y >= 1 && y <= col){if (' ' == board[x - 1][y - 1]){board[x - 1][y - 1] = '*';break;}else{printf("该内容被占用，请重新选择\n");}}else{printf("坐标非法，请重新输入\n");}}}
test.c
play_move(board, Row, Col);//打印棋盘Displayboard(board, Row, Col);
玩家下棋完，我们开始电脑下棋，但是我们在这里电脑下棋完成的只是随机下棋
game.h
void computer_move(char board[Row][Col], int row, int col);
game.c
void computer_move(char board[Row][Col], int row, int col)
{int x = 0;int y = 0;printf("电脑下棋\n");while (1){x = rand() % row;y = rand() % col;if (board[x][y] == ' '){board[x][y] = '#';break;}}}
电脑下棋和玩家下棋是一个循环，且随机，这个时候要用到我们的rand函数，同时要用到srand，还有时间戳的这样一个概念，这些都在猜数字里讲过
那我们接下来就是要思考怎么产生x = rand() % row; y = rand() % col;这样产生坐标，思考这个我们需要思考怎么才能判断输赢，判断三子棋的输赢就是对角线或者行和列要满足，那么我们就做这样的一个函数来实现
test.c
while (1){//玩家下棋play_move(board, Row, Col);Displayboard(board, Row, Col);ret=is_win(board,Row,Col);if (ret != 'C'){break;}//电脑下棋computer_move(board, Row, Col);Displayboard(board, Row, Col);ret = is_win(board, Row, Col);if (ret != 'C'){break;}}if (ret == '*'){printf("玩家赢了\n");}else if (ret == '#'){printf("电脑赢了\n");}else{printf("平局\n");}Displayboard(board, Row, Col);//再次打印棋盘
}
*玩家赢
#电脑赢
C平局
