C++应用：简易五子棋游戏

在实现五子棋小游戏时，首先应该分为棋盘和玩家，我们先定义两个类：chessboard、player。分别提供棋盘的构造和玩家及游戏规则的确定。下面我们看下代码：

chessboard.h: 对棋盘chessboard类型进行定义

#ifndef _CHESSBOARD_H_
#define _CHESSBOARD_H_

#include <iostream>

using namespace std;

class ChessBoard    //棋盘
{
public:
enum{ROW = 31, COL = 31};    //整个棋盘所占的行数和列数
char cSquare[ROW+1][COL+1];      //定义一个字符数组，用来打印棋盘
public:
ChessBoard();                //棋盘构造函数
void show();                 //棋盘的显示
~ChessBoard(){}              //析构函数
};
#endif

chessboard.cpp

#include <iostream>
#include <cstdlib>
#include "chessboard.h"

using namespace std;

//构造函数
ChessBoard::ChessBoard()
{
for(int i = 1; i <= ROW - 2; i += 2){     //将棋盘隔行放入‘-’.
for(int j = 1; j <= COL - 2; j += 2){
cSquare[i][j] = ' ';
cSquare[i][j+1] = '|';
cSquare[i+1][j] = '-';
cSquare[i+1][j+1] = '-';
}
}
//围出棋盘的四周
for(int j = 0; j < COL; j ++)
cSquare[0][j] = cSquare[ROW-1][j] = '-';
for(int i = 0; i < ROW; i ++)
cSquare[i][0] = cSquare[i][COL-1] = '|';

//空处棋盘落子空间
cSquare[ROW][0] = ' ';
cSquare[0][COL] = ' ';
//在最后以行打印出行、列下标0，1,2 ... A，B，C ...
for(int i = 1; i < 20; i += 2){
cSquare[i][COL] = i / 2 + 48;
cSquare[i+1][COL] = ' ';
cSquare[ROW][i] = i / 2 + 48;
cSquare[ROW][i+1] = ' ';
}
for(int j = 21; j < COL; j += 2){
cSquare[ROW][j] = j / 2 + 55;
cSquare[ROW][j+1] = ' ';
}
for(int j = 21; j < ROW; j += 2){
cSquare[j][COL] = j / 2 + 55;
cSquare[j+1][COL] = ' ';
}
}
void ChessBoard::show()
{
system("clear");       //清除缓存区数据
//显示棋盘
for(int i = 0; i <= ROW; ++i){
for(int j = 0; j <= COL; ++j)
cout << cSquare[i][j] << ' ';
cout << endl;
}
}

player.h:定义player类

#ifndef _PLAYER_H_

#include <iostream>
#include <string>
#include "chessboard.h"

using namespace std;

void attachToBoard(ChessBoard* ptBoard){m_ptBoard = ptBoard;}
bool isInChessBoard(int x, int y) const;  //棋子是否罗在棋盘内
bool HisLine(int x, int y) const;   //判断水平方向是否连够5个棋子

下面给出一些运行结果:









最后一个插进去满5个后显示赢，结束程序：



上面代码只实现了简单功能，图形画界面看起来并不是很好，还有很大改进空间。
