三子棋的实现

C语言实现三子棋

 

C语言实现三子棋关键是运用到二维数组的知识，使用多文件编程来实现这个程序，我们需要建立一个头文件，两个源文件来实现：

main.c
chess.c
chess.h

如下图所示,玩家的棋为字符 ‘x’,电脑的棋为字符 ‘0’ 

 

                                 

接下来，我们看一下具体的代码实现：

首先，要完成对头文件的声明：

#ifndef _CHESS_H_
#define _CHESS_H_

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

#define ROW 3
#define COL 3

#define PLAYER_COLOR 'X'
#define COMPUTER_COLOR 'O'

#pragma warning(disable:4996)

void Game();
void InitBoard(char board[][COL], int row, int col);
void ShowBoard(char board[][COL], int row, int col);
void PlayerMove(char board[][COL], int row, int col);
void Judge(char board[][COL], int row, int col);
void ComputerMove(char board[][COL], int row, int col);



#endif

 

 两个源文件：

#include "chess.h"
void InitBoard(char board[][COL], int row, int col)
{
	int i = 0;
	for (; i < row; i++)
	{
		int j = 0;
		for (; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}
void ShowBoard(char board[][COL], int row, int col)
{
	int i;
	for (i = 0; i < row; i++)
	{
		printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);
		if (i != row - 1)
			printf("---|---|--- \n");
	}
}
void PlayerMove(char board[][COL], int row, int col)
{
	while (1)
	{
		int x = 0;
		int y = 0;
		printf("please enter pos<x,y>:  ");
		scanf("%d %d", &x, &y);
		if (x >= 1  &&  x <= 3  &&  y >= 1  &&  y <= 3 )
		{
			if (board[x - 1][y - 1] == ' ')
			{
				board[x - 1][y - 1] = PLAYER_COLOR;
				break;
			}
			else{
				printf("Enter error,Try Again!\n");
			}
		}
	}
}

int FullBoard(char Board[][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++){
		for (j = 0; j < col; j++){
			if (Board[i][j] == ' '){
				return 0;
			}
		}
	}
	return 1;
}


char Judge(char Board[][COL], int row, int col)     
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++){      
		if (Board[i][0] == Board[i][1] && Board[i][1] == Board[i][2] && Board[i][0] != ' '){
			return Board[i][0];
		}
	}
	for (i = 0; i < col; i++){     
		if (Board[0][j] == Board[1][j] && Board[1][j] == Board[2][j] && Board[0][j] != ' '){
			return Board[0][j];
		}
	}
	if (Board[0][0] == Board[1][1] && Board[1][1] == Board[2][2] && Board[0][0] != ' '){    
		return Board[0][0];
	}
	else if (Board[0][2] == Board[1][1] && Board[1][1] == Board[2][0] && Board[2][0] != ' '){
		return Board[0][2];
	}
	if (FullBoard){  
		return 'N';
	}
	else{
		return 'E';   
	}
}

int GetRandom(int start, int end)
{
	return rand() % end+1;
}
void ComputerMove(char board[][COL], int row, int col)
{
	while (1)
	{
		int x = GetRandom(1,3);
		int y = GetRandom(1,3);
		
			if (board[x - 1][y - 1] == ' ')
			{
				board[x - 1][y - 1] = COMPUTER_COLOR;
				break;
			}
	}
}

void Game()
{
	char result = '\0';
	char board[ROW][COL];
	InitBoard(board, ROW, COL);
	ShowBoard(board, ROW, COL);
	srand((unsigned int)time(NULL));
	while (1){
		PlayerMove(board, ROW, COL);
		ShowBoard(board, ROW, COL);
		result=Judge(board, ROW, COL);
		if (result != 'N'){
			break;
		}
		ComputerMove(board, ROW, COL);
		ShowBoard(board, ROW, COL);
		result=Judge(board, ROW, COL);
		if (result != 'N'){
			break;
		}
	}
	switch (result){
	case 'X': //you win
		break;
	case 'O': //computer win
		break;
	case 'E': //Equal
		break;
	default:
		printf("bug?!\n");
		break;
	}



	//memset(board, ' ', sizeof(board));
	printf("再来一局？\n");
}

#include "chess.h"

void ShowMenu()
{
	printf("####################################\n");
	printf("#####  1.Play         2.Exit  ######\n");
	printf("####################################\n");
	printf("Please Select:  ");
}

int main()
{
	int select = 0;
	int quit = 0;
	while (!quit)
	{
		ShowMenu();
		scanf("%d", &select);
		switch (select)
		{
		case 1:
			Game();
			break;
		case 2:
			printf("byebye!\n");
			quit = 1;
			break;
		default:
			printf("您输入有误，请重新输入!\n");
			break;
		}
	}
	system("pause");
	return 0;
}

 实际上与我们自己的思考一样，计算机采用我们的思维完成了这个游戏：
