第七周项目（3）-多文件组织角色类

head头文件声明：

#ifndef GAME_H_INCLUDED

#define GAME_H_INCLUDEDusing namespace std;

class Weapon

{

public:

 Weapon(string wnam,int f);

 int getForce();private:string wname; //名称

int force; //威力

};

class Role

{

public: Role(string nam,int b, string wnam,int f); //构造函数

~Role(); //析构函数

void eat(int d);//吃东西，涨d血

void attack(Role &r); //攻击别人，自己涨血，同时失血

bool isAlived(); //是否活着

void show(); //显示

private:

string name;

 int blood;

 Weapon weapon;

 bool life;

};

#endif // GAME_H_INCLUDED

 

文件role.cpp，实现角色类成员函数：

#include <iostream>

#include "game.h"

usingnamespace std;

Role::Role(string nam,int b, string wnam,int f):name(nam),blood(b),weapon(wnam,f)

{

 if(blood>0) life=true;else life=false;

}

Role::~Role()

{ cout<<name<<"退出江湖..."<<endl;}

void Role::eat(int d)//吃东西，涨d血

{

 if(isAlived())

blood+=d;}

void Role::attack(Role &r)//攻击别人，涨1血

{

if(isAlived())

{

    blood+=weapon.getForce();

    r.blood-=weapon.getForce();

    if(r.blood<=0) r.life=false;

 }

}

bool Role::isAlived()//是否活着

{ return life;}

void Role::show()//显示

{ cout<<name<<" has "<<blood<<" blood, it is ";

if(isAlived())

cout<<"alived.";

 else cout<<"dead.";

cout<<endl;}

 

文件weapon.cpp，实现weapon类成员函数：

#include <iostream>

#include "game.h"usingnamespace std;

Weapon::Weapon(string wnam, int f):wname(wnam),force(f) {}

int Weapon::getForce()

{

return force;

}

 

主函数（测试函数）：

#include <iostream>

#include "game.h"

using namespace std;

int main( )

{

 Role mary("Mary", 500, "TuLong",200);

 Role jack("Jack", 10, "YiTian", 180);

cout<<"---begin---"<<endl;

mary.show(); jack.show(); cout<<"---1st round---"<<endl;

jack.attack(mary);

 mary.show();

jack.show();

 cout<<"---2nd round---"<<endl;

mary.attack(jack);

mary.show();

jack.show();

 cout<<"---end---"<<endl;

return 0;

}
