关于c++指向对象的指针

#include<iostream>

#include<string>

class Pet

{

	public:

	Pet(std::string thename);

	void FREE_TEST();

	void FOOK_TEST();

	void EAT_TEST();

	protected:

	std::string name;

};

class dog:public Pet

{

	public:

	dog(std::string thename);

	

	void CLIMB();

};

class cat:public Pet

{

	public:

	cat(std::string thename);

	

	void KIDDING_TEST();

	

};

Pet::Pet(std::string thename)

{

	name = thename;

}

void Pet::FREE_TEST()

{

	std::cout<<name <<"\n"<<"FREE TEST  OK"<<std::endl;

}

void Pet::FOOK_TEST()

{

	std::cout<<name <<"FOOK TEST OK"<<std::endl;

}

void Pet::EAT_TEST()

{

	std::cout<<name <<"EAT TEST OK "<<std::endl;

}

dog::dog(std::string thename):Pet(thename)

{

}

void dog::CLIMB()

{

	std::cout<<"CLIIMB TEST OK"<<std::endl;

}

cat::cat(std::string thename):Pet(thename)

{

}

void cat::KIDDING_TEST()

{

	std::cout<<"KIDDING TEST OK "<<std::endl;

}

int main()

{

   	Pet *dog = new dog("123");

   	Pet *cat = new cat("546456");

   	//dog->CLIMB();

   	//dogFREE_TEST();

   	//dog.FOOK_TEST();

   	//dog.EAT_TEST();

   	

   	//cat->KIDDING_TEST();

   	//cat.FREE_TEST();

   	//cat.EAT_TEST();

   	//cat.FOOK_TEST();

	return 0;

}

最后编译提示 dog和cat 不是一个type
本人愚笨,还请各位大神指教

要注意变量命名规则。。。

    return 0;
}

谢谢了...我太粗心了

发成冲突了，你的变量名和构造函数的调用同名

好吧是我没认真看.... 谢谢了
