这是C语言小游戏三子棋的代码实现

test.c文件是用来测试的部分

game.h文件是用来声明我们说写出的函数

game.c文件是用来编写我们的功能实现函数部分

1.test.c

#define  _CRT_SECURE_NO_WARNINGS 1
#include"game.h"
void menu()
{printf("*************************\n");printf("*******   1.play  *******\n");printf("*******   2.exit  *******\n");printf("*************************\n");
}void game()
{//存放玩家或者电脑的落子情况char board[ROW][COL];char ret = 0;//初始化棋盘为全空格---->用init_board函数init_board(board, ROW,COL);//打印棋盘---->print_boaardprint_board(board, ROW, COL);while (1){player_move(board, ROW, COL);//玩家下棋实现print_board(board, ROW, COL);//打印//判断输赢ret=is_win(board,ROW,COL);if (ret != 'C'){break;}computer_move(board, ROW, COL);//电脑下棋print_board(board, ROW, COL);//判断输赢ret = is_win(board, ROW, COL);if (ret != 'C'){break;}}if (ret == '#')printf("电脑赢\n");else if (ret == '*')printf("玩家赢\n");else if (ret == 'Q')printf("平局\n");

//判断输赢的代码：电脑赢了？  玩家赢了？  平局？  继续进行？
//电脑赢：#
//玩家赢：*
//平局：Q
//游戏继续：C
void test()

}
int main()

2.game.h

#define COL 3 //列
