三子棋游戏（通过改变宏定义可以变成五子棋），玩家与电脑下棋

1.创建项目

新建项目，并在源文件中添加test.c、game.c文件，在头文件中添加game.h文件。

2.主函数编写

int main()
{srand((unsigned int)time(NULL));//设置随机数的生成起点int input = 0;do{menu();//菜单打印printf("请选择\n");scanf("%d", &input);switch (input){case 1:printf("开始游戏\n");game();break;case 0:printf("退出游戏\n");break;default:printf("选择错误\n");}} while (input);return 0;
}

3.菜单函数编写

打印菜单栏

//菜单打印
void menu()
{printf("*******   三子棋   ******\n");printf("*****1. play 0. exit*****\n");printf("************************\n");}

4.宏定义棋盘行和列

通过更改ROW、COL后面数字可以改变棋盘的行列。改变CON后面的数组可以更改为棋数限制，可以改成4子棋，五子棋。

#define ROW 3
#define COL 3
#define CON 3

5.棋盘初始化

初始化棋盘，使棋盘内容为”空“

//棋盘初始化
void board_Init(char board[ROW][COL], int row, int col)
{int i = 0;int j = 0;for (i = 0; i < row; i++){for (j = 0; j < col; j++){board[i][j] = ' ';}}
}

6.打印棋盘

第一种写法，这种写法将行和列写死了，后续无法通过宏定义控制行列。

//打印棋盘
//第一个版本
void board_Display(char board[ROW][COL], int row, int col)
{int i = 0;for (i = 0; i < row; i++){//打印数据printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);//打印分隔符if (i < row-1)printf("---|---|---\n");}
}

版本二：

用循环的方式写，这种方法可以使用宏定义棋盘数

//打印棋盘Mark2
void board_Display2(char board[ROW][COL], int row, int col)
{int i = 0;for (i = 0; i < row; i++){//打印数据//printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);int j = 0;for (j = 0; j < col; j++){printf(" %c ", board[i][j]);if (j < col - 1)printf("|");}printf("\n");//打印分隔符if (i < row - 1){//printf("---|---|---\n");int j = 0;for (j = 0; j < col; j++){printf("---");if (j < col - 1)printf("|");}printf("\n");}}
}

7.玩家下棋

//玩家下棋
void Player_move(char board[ROW][COL], int row, int col)
{int x = 0;int y = 0;printf("玩家下棋\n");while (1){printf("玩家请选择下棋位置\n");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;}elseprintf("坐标已被占用，请重新选择位置\n");}elseprintf("坐标非法，请重新输入\n");}
}

8.电脑下棋

//电脑下棋
//找没有下棋的位置随机下棋
void Computer_move(char board[ROW][COL], int row, int col)
{printf("电脑下棋\n");int x = 0;int y = 0;while (1){x = rand() % row;//0-2y = rand() % col;//0-2if (board[x][y] == ' '){board[x][y] = '#';break;}}}

9.平局判断

//平局判断
//满了返回1
//不满返回0
int IsFull(char board[ROW][COL], int row, int col)
{int i = 0;int j = 0;for (i = 0; i < row; i++){for (j = 0; j < col; j++){if (board[i][j] == ' '){return 0;}	}}return 1;
}

10.输赢判断

方案一：这种判断方法不能用宏定义更改行列。将程序写死了。

//判断输赢
//
//玩家赢-'*'
//电脑赢-'#'
//平局-'Q'
//游戏继续-'c'
//
char IsWin(char board[ROW][COL], int row, int col)
{//行int i = 0;for (i = 0; i < row; i++){if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')return board[i][1];}//列int j = 0;for (j = 0; j < col; j++){if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[1][j] != ' '){return board[1][j];}}//对角线if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' '){return board[1][1];}if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' '){return board[1][1];}//平局if (IsFull(board,row,col)){return 'Q';}//游戏继续return 'C';
}

方案二：

这种方法可以使用宏定义通过更改count的值来更改棋数限制（可以改成四子棋，五子棋）。

//判断输赢Mark2
char IsWin2(char board[ROW][COL], int row, int col, char tmp)//判断输赢，返回字符
{int i = 0;int j = 0;int count = 0;//判断行for (i = 0; i < ROW; i++)//判断是否有三个字符相同{int count = 0;for (j = 0; j < COL; j++){if (board[i][j] != tmp)//有一个不同就break跳出本次循环break;elsecount++;//有一个相同count就+1if (count == CON)//当count等于3时就代表一行中有三个相同return tmp;//当一行中有三个相同的字符时就代表该字符所对应的赢了返回该字符}}//判断列for (j = 0; j < COL; j++)//同理判断一列中是否有三个字符相同{int count = 0;for (i = 0; i < ROW; i++){if (board[i][j] != tmp)break;elsecount++;if (count == CON)return tmp;}}//判断//*//  *//    * //对角线方向for (count = 0, i = 0; i < ROW; i++)//判断从左往右的直线三个字符是否相同{if (board[i][i] != tmp)break;elsecount++;if (count == CON)return tmp;}//判断//      *//   *//*//对角线方向for (count = 0, j = COL - 1, i = 0; j >= 0, i <ROW; j--, i++)//判断从左往右的直线{if (board[i][j] != tmp)break;elsecount++;if (count == CON)return tmp;}//平局if (IsFull(board, row, col)){return 'Q';}//游戏继续return 'C';
}

11.game函数

game()
{char ret = 0;char board[ROW][COL] = { 0 };//棋盘初始化board_Init(board,ROW ,COL );board_Display2(board, ROW, COL);//下棋while (1){//玩家下棋Player_move(board,ROW,COL);//判断输赢//ret = IsWin(board,ROW,COL);ret = IsWin2(board, ROW, COL, '*');if (ret != 'C'){break;}board_Display2(board, ROW, COL);//电脑下棋Computer_move(board, ROW, COL);//判断输赢//ret = IsWin(board, ROW, COL);ret = IsWin2(board, ROW, COL, '#');if (ret != 'C'){break;}board_Display2(board, ROW, COL);}if (ret == '*'){printf("玩家赢\n");}else if (ret == '#'){printf("电脑赢\n");}else{printf("平局\n");}board_Display2(board, ROW, COL);
}

13.结语：

以上就是用C语言做的简单的三子棋游戏，这个不止是三子棋游戏，可以通过更改宏定义让他变成五子棋等等，缺点是对手电脑是用随机数生成的，它所下的位置是随机的，所以我们想输都难，后续可以尝试写一个让电脑聪明点的函数，体验会更好一些。
