C++20 will be the next big C++ standard after C++11. As C++11 did, C++20 will change the way we program modern C++. This change is particularly true for Ranges, Coroutines, Concepts, and Modules. To understand this next big step in the evolution of C++, let me put it in this post in the historical context of […]
I’m happy to announce. I added a new chapter to lock-based concurrent data structures to my book “Concurrency with Modern C++”. Now, you get 550 pages of concurrency in C++ and more than 140 runnable examples. Here is more info: https://leanpub.com/concurrencywithmodernc
The C++ core guidelines have about twenty naming and layout rules. A few of them are obvious; a few of them may be controversial. Let’s see what I mean.
The lifetime safety profile in the C++ core guidelines boils down to one issue: don’t dereference a possible invalid pointer. A pointer may be invalid because it is not initialized or the nullptr. A pointer may also point beyond its rage or to a deleted object.
Today’s post concerns the second C++ Core Guidelines: Bounds Safety profile. The goal of the profile bounds safety is 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 initialize 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.
