If you’ve programmed in (or studied) C++ long enough, like you have read Scott Meyers’s Effective C++, which is a book organized in, jokingly, commandments like ‘thou shall make destructors virtual’. There’s a lot of stuff to remember.

I’ve found an approach to make the ideas stick: by understanding the rationale behind these commandments through the lens of ‘What would you do if you were to make C++ (features) out of C?‘

C++ is not a language designed from scratch. A lot of quirks and oddities in C++ came straight from the philosophy and the language features naturally available in C. With the right jargons (concepts), you will find a lot of the seemingly counter-intuitive behavior ‘it ought to be like this because of (insert design choice here)‘.

This is what we are going to explore in the “Rational Behind C++ Commandments” (RBCC) blog post series which came from my notes when I was going through Scott Meyer’s book. Once you get the ideas, you should be able to come up with the rules in Effective C on your own (so you don’t have to blindly remember them).
