pointer to members

hi, I've this simple problem with "thinking in c++" page 476; the examples seems wrong or not completely and compiler gets an errror:

class HowMany2 {
   std::string name;
public:	
	std::string getName() const ;
};
//main.cpp
std::string (HowMany2::*fp)() const = &HowMany2::getName(); //compiler require a static method
int main() {
   fp = &HowMany2::getName();
}

class HowMany2 {
   std::string name;
public:	
	std::string getName() const ;
};
//main.cpp
std::string (HowMany2::*fp)() const = &HowMany2::getName(); //compiler require a static method
int main() {
   fp = &HowMany2::getName();
}

To copy to clipboard, switch view to plain text mode 

What's wrong?

It should be:

class HowMany2 {
    int val;
public:
    int getVal() const {
        return val;
    }
};
//main.cpp
int (HowMany2::*fp)() const = &HowMany2::getVal;

class HowMany2 {
    int val;
public:
    int getVal() const {
        return val;
    }
};
//main.cpp
int (HowMany2::*fp)() const = &HowMany2::getVal;

To copy to clipboard, switch view to plain text mode 

Are you sure that's the example from the book?

yes it's the same but I changed the variabiles names;
Now it works: it was the "()" at the end of getName(); (I'm sorry)

thanks.
