Quick Q:Why does std::set seem to force the use of a const_iterator?

By Adrien Hamelin | Aug 5, 2016 01:57 PM | Tags: basics

Quick A: A set does not allow the modification of its keys.

Recently on SO:

Why does std::set seem to force the use of a const_iterator?

A set is like a map with no values, only keys. Since those keys are used for a tree that accelerates operations on the set, they cannot change. Thus all elements must be const to keep the constraints of the underlying tree from being broken.

Quic Q: Is the new C++ return syntax limited?

By Adrien Hamelin | Jul 25, 2016 02:07 PM | Tags: c++11 basics

Quick A: No, there is a specified syntax for it.

Recently on SO:

Is the new C++ return syntax limited?

Yeah, this is not something you'd normally guess.

virtual auto what() const noexcept -> const char * override;

This is just the order you have to use. The syntax could have been different, probably, but this is what we've got.

by Malte Langkabel

From the article:

I often hear people getting confused when talking about parameters and arguments. That confusion grows even stronger when one of them knows the difference but the other one doesn’t. So let’s shed some light on this issue and spread the knowledge! Programming involves talking to each other but that doesn’t have to be more painful than it already is
