C++基础-类的(无参数)继承

类的继承: 当使用class Pig:public Animal{} 就可以继承Animal里面的属性，

类的函数改写: 对于继承父类的属性，可以在子类里面重新被定义和改写

#include <iostream>

class Animal{
public:
    std::string mouth;

    Animal();
    ~Animal();
    void eat();
    void sleep();
    void drool();
};

Animal::Animal() {
    std::cout << "请开始你的表演" << std::endl;
}

Animal::~Animal() {
    std::cout << "游戏结束" << std::endl;
}

void Animal::eat() {
    std::cout << "正在吃饭" << std::endl;
}

void Animal::sleep() {
    std::cout << "我正在吃饭" << std::endl;
}

void Animal::drool() {
    std::cout << "我正在流口水" << std::endl;
}


class Pig : public Animal {
public:
    void eat();
    void climb();
};

void Pig::climb() {
    std::cout << "我是猪我会爬树" << std::endl;
}

void Pig::eat() {
    std::cout << "猪正在吃饭" << std::endl;
}

class Turble : public Animal {
public:
    void eat();
    void swim();
};

void Turble::swim() {
    std::cout << "小乌龟正在游泳" << std::endl;
}
void Turble::eat() {
    std::cout << "小乌龟正在吃饭" << std::endl;
}
int main() {

    Turble turble;
    Pig pig;

    turble.eat();
    turble.swim();
    pig.eat();
    pig.climb();
