C language to realize the game of sanbang

Use C language to implement a simple man-machine versus three-bang game

Go directly to the code:

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 contains the main function and test code

#define _CRT_SECURE_NO_WARNINGS 1
#include "game.h"

//打印菜单

	printf("****欢迎来到三子棋游戏****\n");

Start playing now

1. First enter the game print menu, you can choose to start the game or exit the game, choose 1 to start the game 2. After starting the game, print the format of the board, and then choose
the player to go first or the computer to go first

Go first, then the player enters the coordinates to move



4, the final player wins, and the game menu is printed in a loop. You can choose to start the game repeatedly, or exit the game
