C++ Do i need to define header guards for nested classes?

Question

Please see the given example:

#ifndef OUTER_H
#define OUTER_H

class Outer
{
    class Inner
    {
    public:
        Innner();
    };

};

#endif

My question is: Do I need to create a header guard somewhere for my Inner class, or just one for the whole file?

Header guards are for the whole header file, not individual classes. — Galik, Mar 17 '17 at 00:43

As your main header guard contains everything, and I'm assuming that is a .h file, which means it contains only declarations (or at least it should), then everything that is within the guard is guarded. So in short, no, you don't need an extra guard.
