C语言程序设计-实现三(N)子棋游戏

画自己喜欢的画，别停笔小艺术家。

实现三子棋：

test.c  //测试游戏的逻辑

#include "game.h"//自己的头文件

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

void game()
{
	char ret = 0;
	char board[ROW][COL] = { 0 };
	//初始化棋盘的函数
	InitBoard(board, ROW, COL);
	DispalyBoard(board, ROW, COL);
	//下棋
	while (1)
	{
		PlayerMove(board,ROW,COL);
		//判断输赢
		ret = Iswin(board,ROW,COL);
		if (ret != 'C')
		{
			break;
		}
		DispalyBoard(board, ROW, COL);
		ComputerMove(board,ROW,COL);
		//判断输赢
		ret = Iswin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		DispalyBoard(board, ROW, COL);
	}
	if (ret == '*')
	{
		printf("玩家赢\n");
	}
	else if (ret == '#')
	{
		printf("电脑赢\n");
	}
	else
	{
		printf("平局\n");
	}
	DispalyBoard(board, ROW, COL);
}

int main()
{
	srand((unsigned int)time(NULL));//设置随机数的生成起点
	int input = 0;
	do
	{
		menu();//打印菜单
		printf("请选择：>");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:

}

game.h  //游戏代码的声明  （函数声明，符号定义）

#pragma once

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

#define ROW 3
#define COL 3

//初始化棋盘
void InitBoard(char board[ROW][COL],int row,int col);//row是行，col是列

//打印棋盘
void DispalyBoard(char board[ROW][COL], int row, int col);

//玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col);

//电脑下棋
//找没有棋子的地方随机下棋
void ComputerMove(char board[ROW][COL], int row, int col);

//判断输赢
//玩家赢-'*'
//电脑赢-'#'
//平局-'Q'
//继续-'C'
char Iswin(char board[ROW][COL], int row, int col);

 更改ROW和COL的大小可以改变棋盘大小，但是要注意行，列，对角线的输赢判断写死了，改动棋盘大小也要更改行，列，对角线的输赢判断。这个可以后续自己优化。
