Taking into account the following classes:

class Class1{

public: Class1();

int getX();

int getY();

int setX(int);

int setY(int);

void operator +=(Class1 &tmp);

int operator *(int n);

void operator *=(Class1 &tmp);

Class1 *operator +=(Class1 &tmp);

private: int x;

int y; };

Class Class2:public Class1{

public: Class2();

int getZ();

void setZ(int );

private:

int z;};

Class2 objects also have the attributes of Class1?
