Question

I just wanted to know if I can point to class using this implementation:

class hello
{
    public:
         void blah();
};

typedef hello* pointer_to_class_hello;

pointer_to_class _hello p1;

So now, does this new pointer p1 point to the class “hello”?

Answer 1

class hello
{
    public:
         void blah();
};

typedef hello* pointer_to_class_hello;

pointer_to_class_hello p1;

Does this new pointer p1 point to the class “hello”? No, pointers in C++ point to objects (a class is a type), be it with automatic, static or dynamic storage duration (or to functions). Besides that, p1 is uninitialized, so it doesn’t yet point to any valid location.

hello H;
p1 = &H;  // Now it does, it points to H.
