一.game.h（游戏头文件）

#pragma once
#include<stdio.h>
#include<stdlib.h>
#include <time.h>

#define COW 6
#define VER 6

void InitBoard(char board[COW][VER], int cow, int ver);

void Displayboard(char board[COW][VER], int cow, int ver);

void Playermove(char board[COW][VER], int cow, int ver);

void Computermove(char board[COW][VER], int cow, int ver);

char Judgegame(char board[COW][VER], int cow, int ver);

int  Draw(char board[COW][VER], int cow, int ver);

二、test.c（测试代码）

#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"

void menu() 
{
	printf("************************************\n");
	printf("*******1.开始游戏 0.退出游戏********\n");
	printf("************************************\n");
}
void game()
{
	int ret = 0;
	char board[COW][VER] = { 0 };
	InitBoard(board, COW, VER);
	Displayboard(board, COW, VER);
	while (1)
	{
		Playermove(board, COW, VER);
		Displayboard(board, COW, VER);
		char ret = Judgegame(board, COW, VER);


		if (ret == '*')
		{
			printf("玩家赢\n");
			break;
		}

		Computermove(board, COW, VER);
		Displayboard(board, COW, VER);
		ret = Judgegame(board, COW, VER);

		if (ret == '#')
		{
			printf("电脑赢\n");
			break;
		}
		if (ret == 'P')
		{
			printf("平局\n");

		}
	}
	printf("游戏结束\n");

}


int main()
{
	int input = 0;
	srand((unsigned int)time(NULL));
	do {
		menu();
		printf("请输入一个数字：>>>");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			printf("游戏结束\n");
			break;
		default:
			printf("输入错误，请重新输入!!!!!\n");
			break;
		}
	} while (input);
	return 0;
}

三、game.c（游戏模块）

1.游戏操作

2.游戏输赢判断

#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"
void InitBoard(char board[COW][VER], int cow, int ver)

		}
	}
}

void Displayboard(char board[COW][VER],int cow,int ver)

	int i = 0;
	int j = 0;
	for (i = 0; i < cow;i++)
	{
		for (j = 0; j < ver; j++)
		{
			printf(" %c ",board[i][j]);
			if(j<ver-1)
			printf("|");
		}
		printf("\n");
		for (j = 0; j < ver; j++)
		{
			if(i<cow-1){
				printf("---");
				if (j < ver - 1)
					printf("|");
			}
		}
		printf("\n");
	}
}
void Playermove(char board[COW][VER],int cow,int ver)
{
	while (1)
	{
		int x = 0;
		int y = 0;
		printf(">>>>>>>>>>>>>>>>>>>玩家走<<<<<<<<<<<<<<<<\n");
		printf("请输入一个坐标比如（x y）括号不用：>>>");
		scanf("%d%d", &x, &y);
		if (x >= 1 && x <= cow && y >= 1 && y <= ver)
		{
			if (board[x-1][y-1] == ' ')
			{
				board[x - 1][y - 1] ='*';
				break;
			}
			else
			{

			}
		}
		else
		{

		}
	}

}

void Computermove(char board[COW][VER], int cow, int ver)
{
	printf(">>>>>>>>>>>>>>>>>>>电脑走<<<<<<<<<<<<<<<<\n");
	while(1)
