【c++】this 指针和类的继承

典型例子：

this 指针指向当前类生成的对象

类的继承

#include <iostream>
#include <string>

class Animal
{
public:
std::string mouth;

void eat();
void sleep();
void droop();
};

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

class Turtle: public Animal
{
public:
void swim();
};

void Animal::eat()
{
std::cout<<"I'm sleeping!!!"<<std::endl;
}

void Animal::droop()
{
std::cout<<"I'm drooping!!!"<<std::endl;
}

void Pig::climb()
{
std::cout<<"I'm climbing!!!"<<std::endl;
}

void Turtle::swim()
{
std::cout<<"I'm swimming!!!"<<std::endl;
}
int main()
{
Pig pig;
Turtle turtle;

pig.eat();
turtle.swim();

return 0;
}
