C++实现五子棋游戏

三子棋、五子棋之类的游戏,非常简单,对于初学者来说是一个不错的练手的小项目,以前用C语言写过三子棋游戏。最近在看C++,所以就想到在三子棋的基础上利用C++语言实现五子棋游戏。

主要功能:

有3个模式:0表示退出、1表示电脑vs玩家、2表示玩家vs玩家。

当一局完成之后选择'y'则又会进入选择模式。

源代码(VS2013编译器下写的):

#include<iostream>

#include<stdio.h>

#include<stdlib.h>

#include <time.h>

using namespace std;

const int N=15; //15*15的棋盘

const char ChessBoardflag = ' '; //棋盘标志

const char flag1='o'; //玩家1或电脑的棋子标志

const char flag2='X'; //玩家2的棋子标志

typedef struct Coordinate //坐标类

{

int x; //代表行

int y; //代表列

}Coordinate;

class GoBang //五子棋类

{

public:

GoBang() //初始化

{

InitChessBoard();

}

void Play() //下棋

{

Coordinate Pos1; // 玩家1或电脑

Coordinate Pos2; //玩家2

int n = 0;

while (1)

{

int mode = ChoiceMode();

while (1)

{

if (mode == 1) //电脑vs玩家

{

ComputerChess(Pos1,flag1); // 电脑下棋

if (GetVictory(Pos1, 0, flag1) == 1) //0表示电脑,真表示获胜

break;

PlayChess(Pos2, 2, flag2); //玩家2下棋

if (GetVictory(Pos2, 2, flag2)) //2表示玩家2

break;

}

else //玩家1vs玩家2

{

PlayChess(Pos1, 1, flag1); // 玩家1下棋

if (GetVictory(Pos1, 1, flag1)) //1表示玩家1

break;

PlayChess(Pos2, 2, flag2); //玩家2下棋

if (GetVictory(Pos2, 2, flag2)) //2表示玩家2

break;

}

}

cout << "***再来一局***" << endl;

char c = 'y';

cin >> c;

if (c == 'n')

break;

}
