Today's post is about the second profile of the C++ Core Guidelines: Bounds Safety. The goal of the profile bounds safety is it that you operate inside the bounds of allocated memory.

What does that mean: type safety by design. Type safety by design just means, that you always initialise your variables, use std::variant instead of a union, or prefer variadic templates and fold expressions to va_arg's.

The C++ core guidelines support three profiles: type safety, bounds safety, and lifetime safety. Thanks to the guideline support library (GSL), you can check your code against these profiles. Today, I start with the profile type safety.

Informally, profiles are a subset of rules of the C++ core guidelines for specific concerns such as type safety, bounds safety, and lifetime safety. Thanks to the guideline support library, they can be checked

Today, I conclude my story to your myths about C++. These myths are around function parameters, the initialisation of class members, and pointer versus references.

Now, it's time to choose the next pdf bundle? You will get all posts, all source files, and a cmake file to the chosen topic.

I was very curious about your C++ myths. In particular, my German readers were quite active. I got a few E-Mails and observed a vivid discussion on Heise Developer.

Demystifying non-rules and myths in C++ is a laborious but absolutely necessary job. The goal is simple: use the powerful tool C++ appropriately.

Of course, you already know many non-rules and myths to C++. Non-rules and myths which we have to argument against when we use modern C++. The supporting section of the C++ core guidelines addresses the most resistant once but also provides alternatives.

Let's recapitulate. In the last two years, I have written about 100 posts to the C++ Core Guidelines. Why? The document answers:  "This document is a set of guidelines for using C++ well. The aim of this document is to help people to use modern C++ effectively.". But my story does not end here. The guidelines have a supporting section.
