c++ / day04

1. 整理思维导图

2. 全局变量，int monster = 10000;定义英雄类hero，受保护的属性string name，int hp,int attck；公有的无参构造，有参构造，虚成员函数 void Atk(){blood-=0;}，法师类继承自英雄类，私有属性 int ap_atk=50；重写虚成员函数void Atk(){blood-=(attck+ap_atk);}；射手类继承自英雄类，私有属性 int ac_atk = 100；重写虚成员函数void Atk(){blood-=(attck+ac_atk);}实例化类对象，判断怪物何时被杀死。(能写多少写多少)

代码

#include 

using namespace std;

int blood =10000;

class Hero
{

protected:

    string name;

    int attck;

public:
    //constructor without param
    Hero(){}

    //constructor with param
    Hero(string name, int attck):name(name), attck(attck)
    {}
    virtual void atk()
    {
         cout << "Hero attck" <child
   Hero *pa = &archer; //parent point -->child
   int count_m = 0;
   int count_a = 0;

   while(1)
   {
       pm->atk();
       count_m++;
       if(blood <=0)
       {
           break;
       }
       pa->atk();
       count_a++;
       if(blood <=0)
       {
           break;
       }

   }
