Test.c#define _CRT_SECURE_NO_WARNINGS 1#include<stdio.h>#include<windows.h>#include"game.h"//调用游戏头文件void main(){char ret = 0;char arr[ROW][COL];init_board(arr);do{display_board(arr);player_move(arr);ret = check_win(arr);if (ret != ' ')break;computer_move(arr);ret = check_win(arr);} while (ret == ' ');display_board(arr);if (ret == 'x')printf("玩家赢得游戏\n");else if (ret=='0')printf("电脑赢得游戏\n");else if (ret == 'q')printf("平局\n");system("pause");     return 0;}

可以多次重复的玩游戏void menu(){printf("1.start   0.exit\n ");}int main(){int input  = 1;while (input){menu();printf("请选择：");    scanf("%d", &input);switch (input){case 1:game();break;case 0:break;}}system("pause");}
