C++ 继承后重载

继承后重载：即先继承，然后再对继承的子类进行重载

#include <iostream>
#include <string>
//吃的参数不同，调用对应的函数
class Animal
{
public:
    Animal(std::string theName);
    void eat();

    void sleep();

private:
    std::string name;
};


class Pig:public Animal
{
public:
    Pig(std::string theName);
    void climb();
    void eat();
    void eat(int eatCount);
};

Animal::Animal(std::string theName)
{
    name = theName;
}

void Animal::eat()
{   
    std::cout<<"(基类)吃（未重载）"<<std::endl;
}


Pig::Pig(std::string theName):Animal(theName)
{

}

void Pig::climb()
{
    std::cout<<"小猪爬树"<<std::endl;
}
void Pig::eat()
{   
    Animal::eat();//基类的吃
    std::cout<<"吃（覆盖基类的吃）"<<std::endl;
}

void Pig::eat(int eatCount)
{   
    std::cout<<"吃（对子类的吃（上面的方法）重载）"<< eatCount <<"碗"<<std::endl;
}

int main()
{
    Pig pig("小猪");
    pig.climb();
    pig.eat();
    pig.eat(15);
    return 0;
}
