C语言小游戏井字棋（三子棋）

1.自定义game.h头文件

#pragma once

#include 

//符号定义
#define Row 3
#define Col 3


//函数声明

//棋盘
void showborad(char board[Row][Col],int row,int col);

//玩家下棋
void playermove(char board[Row][Col]);

//电脑下棋
void computermove(char board[Row][Col]);

//打印棋盘
void displayboard(char board[Row][Col]);

//判断输赢
char Iswin(char board[Row][Col]);

2.game.c游戏函数

#define _CRT_SECURE_NO_WARNINGS
#include "game.h"
#include 


//初始化棋盘

			printf("%c", board[i][j]);
			if (j < col - 1)
			{
				printf("|");
			}

		}
		printf("n");
		for (j = 0; j < col; j++)
		{
			printf("-");

	}

	
}

//电脑下棋
void computermove(char board[Row][Col]) {
	
	printf("电脑下棋n");

	}

}

3.test.c测试文件

#define _CRT_SECURE_NO_WARNINGS 1

#include "game.h"

void menu()
{
	printf("* * * * * * * * * * * * * * * * * * *n");
	printf("* * * * * * 1.play      * * * * * * *n");
	printf("* * * * * * 0.exit      * * * * * * *n");
	printf("* * * * * * * * * * * * * * * * * * *n");
	
}

void game() {
	//存储数组
	char board[Row][Col];
	int row = Row;
	int col = Col;
	//初始化棋盘
	showborad(board,row,col);

	while (1) {
		//玩家下棋
		playermove(board);

		//打印棋盘
		displayboard(board);

		//判断输赢
		char c = Iswin(board);
		if (c == '*')
		{
			printf("玩家获胜！n");
			break;
		}
		else if (c == 'Q')
		{
			printf("平局！n");
			break;
		}
		//电脑下棋
		computermove(board);

		//打印棋盘
		displayboard(board);

		//判断输赢
		char d = Iswin(board);
		if (d == '#')
		{
			printf("电脑获胜！n");
			break;
		}
		else if (c == 'Q')
		{
			printf("平局！n");
			break;
		}
	
	}

	
}

int main()
{
	int input = 0;
	srand((unsigned int)time(NULL));
	do {
		menu();
		printf("请输入：");
		scanf("%d", &input);
		switch (input)

	}while (input);
	


	return 0;
