Programmer - Passing member function pointer to member object in c++

Programmer Question

I have a problem with using a pointer to function in C++. Here is my example:

#include <iostream>

using namespace std;

class bar
{
public:
    void (*funcP)();
};

class foo
{
public:
    bar myBar;
    void hello(){cout << "hello" << endl;};
};

void byebye()
{
    cout << "bye" << endl;
}


int main()
{
    foo testFoo;

    testFoo.myBar.funcP = &byebye;         //OK
    testFoo.myBar.funcP = &testFoo.hello;  //ERROR
    return 0;
}

Compilator returns an error at testFoo.myBar.funcP = &testFoo.hello;:

ISO C++ forbids taking the address of a bound member function to form a
pointer to member function. Say
'&foo::hello'

cannot convert 'void (foo::)()' to 'void ()()' in assignment

So i tried it like this:

class bar
{
public:
    void (*foo::funcP)();
};

But now the compilator adds one more:

'foo' has not been declared

Is there a way make it work?

Thanks in advance for suggestions
