C语言代码实现井字棋游戏
时间：2022-06-23 11:40:09 | 栏目：C代码 | 点击：次
井字棋是一个很常见的小游戏。要求对战双方在一个“井”形的棋盘里分别下“*”棋子或者“#”棋子，谁先连成3个，谁就赢。
本次使用C语言来实现这个小游戏。
由于使用函数较多，所以采用多文件的方式方便梳理代码思路。
本次一共有三个文件：
**
game.h：
包含了game.c文件中函数的声明和库函数的声明。**
#pragma once #define ROW 3 #define COL 3 #include<stdio.h> #include<stdlib.h> #include<time.h> void InitBoard(char board [ROW][COL], int row, int col); //初始化棋盘 void DisplayBoard(char board [ROW][COL], int row, int col); //打印棋盘 void PlayerBoard(char board [ROW][COL], int row, int col); //玩家走 void ComputerBoard(char board [ROW][COL], int row, int col);//电脑走 char IsWin(char board [ROW][COL], int row, int col); //结果判断
game.c：
包含游戏过程中关键函数的函数主体。
#define _CRT_SECURE_NO_WARNINGS
#include"game.h"
void InitBoard(char board[ROW][COL], int row, int col)
