C语言实现三子棋游戏

使用C语言实现一个简单的人机对战三子棋游戏

直接上代码：

game.h

#ifndef __GAME_H__
#define __GAME_H__

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

#define ROW 3//定义标识符常量，固定棋盘的大小，可以根据用户需要随时改变
#define COL 3

void InitBoard(char board[ROW][COL], int row, int col);
void DisplayBoard(char board[ROW][COL], int row, int col);
void PlayerMove(char board[ROW][COL], int row, int col);
void ComputerMove(char board[ROW][COL], int row, int col);
char IfWin(char board[ROW][COL], int row, int col);

#endif //GAME H

test.c 包含主函数以及测试代码

#define _CRT_SECURE_NO_WARNINGS 1
#include "game.h"

//打印菜单
void menu()
{
	printf("***********************\n");
	printf("****欢迎来到三子棋游戏****\n");
	printf("******   1.play  ******\n");
    printf("******   0.exit  ******\n");
	printf("***********************\n");

}

//开始游戏
void game()
{
	char ret;
	int input = 0;
	char board[ROW][COL] = {0};
    InitBoard(board, ROW, COL);
	DisplayBoard(board, ROW, COL);
	printf("在本游戏中，1 表示玩家，2 表示电脑\n");
	printf("请输入选择玩家先走或电脑先走\n");
	scanf("%d",&input);
	if(input == 1)//玩家输入1，玩家先走
	{
		printf("玩家先走\n");
		while(1)
		{
			PlayerMove(board, ROW, COL);
			ret = IfWin(board, ROW, COL);

		}

		    DisplayBoard(board, ROW, COL);
		}

			{
				break;
			}
			DisplayBoard(board, ROW, COL);

			PlayerMove(board, ROW, COL);
			ret = IfWin(board, ROW, COL);
			if(ret == '1')
			{
				break;
			}
			DisplayBoard(board, ROW, COL);
		}

		{

		}
	    if(ret == 'p')
		{
		    printf("平局\n");
		    DisplayBoard(board, ROW, COL);
		}
	}
}

//游戏测试
void test()
{
	int input = 0;
	do{
		menu();
	    printf("请选择：");
	    scanf("%d",&input);
	    switch(input)
	   {

			game();
			break;
		case 0:
			printf("退出游戏\n");
			break;
		default:
			printf("选择错误\n");
			break;
		}
	}while(input);
}

int main()
{
	test();

现在开始玩游戏

1、首先进入游戏打印菜单，可以选择开始游戏或者退出游戏，选择 1 开始游戏
2、开始游戏之后，打印棋盘的格式，然后选择玩家先走或者电脑先走

3、具有谦让精神的我们选择让电脑先走，然后玩家输入坐标落子



4、最终玩家获得胜利，循环打印游戏菜单 可以选择重复开始游戏，或者退出游戏
