Use c language to implement tic-tac-toe chess (with source code, you can run it directly)

学习C语言

源码来源：b站课程以及文件来源
在b站上听这位老师讲的课,自己跟着打了一边代码,分享给大家

需要在同一个工程下创建两个.c 文件,一个.h文件

头文件/函数声明（.h文件）

#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);
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 IsWin(char board[ROW][COL], int row, int col);
int IsFull(char board[ROW][COL], int row, int col);

mian函数（.c文件）

#define _CRT_SECURE_NO_WARNINGS
#include "game.h"

void menu()
{
    
	printf("\n");
	printf("****************************\n");
	printf("***** 井字棋 ****\n");
	printf("***** 请输入1或者0 ****\n");
	printf("***** 1.play 0.exit ****\n");
	printf("****************************\n");
	printf("\n");
}
void game()
{
    
	char ret = 0;
	char board[ROW][COL] = {
     0 };
	//初始化
	InitBoard(board, ROW, COL);
	//打印棋盘
	DisplayBoard(board, ROW, COL);
	//下棋
	while (1)
	{
    
		//玩家下棋
		PlayerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断玩家是否赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
    
			break;
		}
		//电脑下棋
		ComputerMove(board, ROW, COL);
		DisplayBoard(board,ROW, COL);
		//判断电脑是否赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
    
			break;
		}

	}
	if (ret == '*')
	{
    
		printf("玩家赢！\n");
	}
	else if (ret == '#')
	{
    
		printf("电脑赢！\n");
	}
	else if (ret == 'Q')
	{
    
		printf("平局！\n");
	}
}

void test()
{
    
	int input = 0;
	srand((unsigned int)time(NULL));
	do
	{
    
		menu();
		printf("请选择:>");
		scanf("%d", &input);
		switch (input)
		{
    
		case 1:
			game();
			break;
		case 0:
			printf("退出游戏\n");
			break;
		default:
			printf("选择错误,请重新选择！\n");
			break;
		}
	} while (input);
}

int main()
{
    
	test();
	return 0;
}
