Pointer to member function

[Maejie]

Is there an actual advantage of using a pointer to member function ?

I think the syntax looks no good at all ? I can't comprehend much.

struct A
{
    void somefunc(){}
};

void A::somefunc(int i)
{
    int (*uglyPointI)(void*);
    uglyPointI=i;
    //do something
    (*uglyPointI)((void*)&i);
}

Please, don't ask me what I am doing because I actually have no idea what I am doing either. I know I am making a bad question and I hope you would correct it and help me make a better question in the future...Thank you..

If you need one, it would be advantageous to have them.

Admittedly, it seemed confusing to me the first time I glanced them, although I don't see any pointer to member functions in your example.

class TestClass
{
public:
    int someMemberFunction(int n){ return n; }
};

int (TestClass::*memberFunctionPointer)(int) = &TestClass::someMemberFunction;

TestClass t;

int result = (t.*memberFunctionPointer)(42)

There is also std::function, which can be used to "point" to both functions and member functions.

Perhaps you should wait until you do know what you are doing?
