如何用多文件编写三字棋

菜鸟如何写三子棋

1 三子棋设计思路

1. 菜单设计（输入开始，退出游戏）。
2. 游戏模块设计。
   1）初始化棋盘
   2）显示棋盘
   3）开始玩（循环执行：用户走，判断；电脑走，判断）

①下面给出game.h头文件部分

#ifndef __GAME_H__

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

#define ROWS 3    
#define COLS 3

void Meun();
void Game();
void InitBoard(char board[ROWS][COLS], int x, int y);
void DisplayBboard(char board[ROWS][COLS], int x, int y);
void PlayerMove(char board[ROWS][COLS], int x, int y);
void ComputerMove(char board[ROWS][COLS], int x, int y);
char Judge(char board[ROWS][COLS], int x, int y);

#pragma warning(disable:4996)
//#define _CRT_SECURE_NO_WARNINGS 1

#endif __GAME_H__

②下面给出game.c部分代码

#include "game.h"

void Meun()//打印菜单
{
	printf("**************************\n");
	printf("*********  Meun  *********\n");
	printf("       1.Start game.      \n");
	printf("       0.Exit game.       \n");
	printf("**************************\n");
}

void DisplayBoard(char board[ROWS][COLS], int x, int y)//打印棋盘
{
	int i = 0;
	int j = 0;
	for (i = 0; i<x; i++)
	{
		printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);
		//Sleep(1000);
		if (2 != i)printf("---|---|---\n");
	}
}

void Game()//开始游戏
{
	char board[ROWS][COLS];
	char ret = 0;
	InitBoard(board, ROWS, COLS);
	DisplayBoard(board, ROWS, COLS);
	do
	{
		PlayerMove(board, ROWS, COLS);
		ret = Judge(board, ROWS, COLS);
		if ('X' == ret){ printf("Player win!\n"); break; }
		if ('O' == ret){ printf("Computer win!\n"); break; }
		if (' ' == ret){ printf("Dogfall!\n"); break; }
		ComputerMove(board, ROWS, COLS);
		ret = Judge(board, ROWS, COLS);
		if ('X' == ret){ printf("Player win!\n"); break; }
		if ('O' == ret){ printf("Computer win!\n"); break; }
		if (' ' == ret){ printf("Dogfall!\n"); break; }
	} while (1);
}

void InitBoard(char board[ROWS][COLS], int x, int y)//初始化游戏
{
	memset(board, ' ', ROWS*COLS*sizeof(char));
}


void PlayerMove(char board[ROWS][COLS], int x, int y)//玩家玩
{
	int i = 0;
	int j = 0;
	while (1){
		printf("Player input>: ");
		scanf("%d %d", &i, &j);  //输入位置
		if (' ' == board[i - 1][j - 1] \
			&& (i - 1) >= 0 && (i - 1)<x \
			&& (j - 1) >= 0 && (j - 1)<y) {
			board[i - 1][j - 1] = 'X';
			DisplayBoard(board, ROWS, COLS);
			break;
		}
		else printf("Error input!\n");
	}
}
void ComputerMove(char board[ROWS][COLS], int x, int y)//电脑玩
{
	int i = 0;
	int j = 0;
	printf("Computer input>:");
	while (1)
	{
		i = rand() % 3;
		j = rand() % 3;
		if (' ' == board[i][j])//位置合法性检测
		{
			printf("%d %d\n", i + 1, j + 1);
			board[i][j] = 'O';
			DisplayBoard(board, ROWS, COLS);
			break;
		}
	}
}

char Judge(char board[ROWS][COLS], int x, int y)//检测输赢
{
	int i = 0;
	int j = 0;
	int count = 0;
	for (i = 0; i<x; i++){
		if (board[0][i] == board[1][i] && board[0][i] == board[2][i]){
			if ('X' == board[0][i]) return 'X';
			if ('O' == board[0][i]) return 'O';
		}
		if (board[i][0] == board[i][1] && board[i][0] == board[i][2]){
			if ('X' == board[i][0]) return 'X';
			if ('O' == board[i][0]) return 'O';
		}
	}
	if (board[0][0] == board[1][1] && board[0][0] == board[2][2]){
		if ('X' == board[0][0]) return 'X';
		if ('O' == board[0][0]) return 'O';
	}
	if (board[0][2] == board[1][1] && board[0][2] == board[2][0]){
		if ('X' == board[1][1]) return 'X';
		if ('O' == board[1][1]) return 'O';
	}
	for (i = 0; i<x; i++){//判断棋盘是否有子
		for (j = 0; j < y; j++){
			if (' ' != board[i][j]){
				count++;
			}
		}
	}
	if (9 == count)return ' ';
}

③下面给出main.c部分代码

#include "game.h"

int main()        
{
	int input = 0;
	do
	{
		Meun();
		printf("Please select >: ");
		scanf("%d", &input);
		switch (input)
		{
		case 1:Game(); break;
		case 0:printf(" Exit \n"); break;
		default:printf("Error! \n"); break;
		}
	} while (input);
	return 0;
}
