多文件组织多个类程序

用多个cpp文件实现上一个带武器的角色，将头文件保存在.h的文件中。

(1)weapon.h

#ifndef WEAPON_H_INCLUDED
#define WEAPON_H_INCLUDED
#include<string>
using namespace std;
class weapon
{
public:
weapon(string na,int po)
{
name=na;
power=po;
}
int getpower();
string getname();
private:
string name;
int power;
};
#endif // WEAPON_H_INCLUDED
(2)Role.h

#include"weapon.h"
#include<string>
using namespace std;
class Role
{
public:
Role(string nam,int n,string we,int p);
~Role();
void show();
void attack(Role &other);
void eat(int n);
void beAttack(Role &other);
bool isAlive();
string getname();
private:
string name;
int blood;
weapon weapon;
bool life;
};
(3)game.cpp

#include"weapon.h"
#include"Role.h"
#include<iostream>
using namespace std;

string weapon::getname()
{
return name;
}
int weapon::getpower()
{
return power;
}
string Role::getname()
{
return name;
}
void Role::attack(Role &other)
{
if(isAlive())
{
cout<<name<<"使用"<<weapon.getname()<<"攻击"<<other.getname()<<',';
cout<<other.getname()<<"损失"<<weapon.getpower()<<"滴血,";
cout<<name<<"得到"<<weapon.getpower()<<"滴血"<<endl;
blood+=weapon.getpower();
other.blood-=weapon.getpower();
if(other.blood<=0)
life=false;
}
}
void Role::eat(int n)
{
if(isAlive())
cout<<name<<"吃了一个苹果，血量增加"<<n<<"点"<<endl;
blood+=n;
}
void Role::beAttack(Role &other)
{
if(isAlive())
{
cout<<other.getname()<<"使用"<<other.weapon.getname()<<"攻击"<<name<<',';
cout<<name<<"损失"<<other.weapon.getpower()<<"滴血,";
cout<<other.getname()<<"得到"<<other.weapon.getpower()<<"滴血"<<endl;
blood-=other.weapon.getpower();
other.blood+=weapon.getpower();
if(blood<=0)
life=false;
}
}
bool Role::isAlive()
{
return life;
}
Role::Role(string nam,int n,string we,int p):name(nam),blood(n),weapon(we,p)
{
// this->name=nam;
// this->blood=n;
// this->weapon.name=we;
// this->weapon.power=p;
if(blood>0)
life= true;
else
life= false;
}
Role::~Role()
{
if(blood<=0)
cout<<name<<"退出江湖"<<endl;
}

void Role::show()
{
if(blood>0)
cout<<name<<"还剩"<<blood<<"滴血"<<endl;
}(4)main.cpp

#include<iostream>
#include<string>
#include"Role.h"
#include"weapon.h"
using namespace std;
int main( )
{
int i=1;
cout<<"初始状态:"<<endl;
Role mary("Mary", 100,"灵兽刀",90);
Role jack("Jack", 100,"张扬剑",10);
mary.show();
jack.show();
cout<<"第一回合:"<<endl;
mary.attack(jack);
mary.beAttack(jack);
jack.attack(mary);
jack.beAttack(mary);
jack.eat(5);
mary.show();
jack.show();
cout<<"第二回合:"<<endl;
mary.attack(jack);
mary.beAttack(jack);
jack.attack(mary);
jack.beAttack(mary);
mary.show();
jack.show();
return 0;
}
