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;elselife= 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;}
