Question

I’m looking for some best practice advice. If you have a class declared in C++ like so:

class Foo {
public:
    enum { A, B, MAX};
};

Should the enum be accessed like:

Foo::A

or

Foo *var; 
var->A;

Up until today I had always accessed the constant values like Foo::A, rather than through a ptr of the class type. In truth I didn’t even believe it was possible. Has anyone come across when and if each form should be used or should I stick to the tried and tested Foo::A method?

EDIT: made Foo var into Foo *var it was a typo as most people have spotted thanks.

Answer 1

The enum is associated with the class, rather than with instances. So Foo::A is better.
