The sea is full of dangers,


size being only one.


Alluring depths and gruesome beasts


have intertwined in majesty.


The humble one left all alone


sought guidance in a spark of light.


Crashing GCC with 63 Bytes

C++, error, #GCC, #g++, #internal compiler error

Enthusiastically following C++20’s new compile-time capabilities as well as awaiting more powerful ones being promised in upcoming standards, yet being stuck on C++17 [1], I try to take full advantage of the limited C++17-constexpr features. However, without static storage promotion, a constexpr std::string is all but a pipe dream, thereby necessitating the use of a wrapped static pointer; std::string_view.

One does not program against one’s compiler; one programs against the abstract machine defined by the standard.

Book review: A Tour of C++

Avidly writing C as well as golfing in it for over two years, I decided to venture out further in the realm of C-descendent languages, trying to get a foothold in C++.
However, contrary to many other languages with their own closed communities, style guides, best practices and general higher machine abstraction induced ease of use, C++ is a different language. With a rich history spanning multiple decades, millions of users from varying backgrounds and the necessity of enabling low-level hardware communication influencing its design and ability to be used effectively, it is a daunting task to acquire enough knowledge and experience to successfully write a standards-conforming C++ program which accomplishes a desired task.
Adding to this the plethora of textbooks supposedly correctly presenting their selected corner of the language and with that the immense danger of a poorly written textbook supplying a misleading first impression thus wrecking the fundamental knowledge of the language as well as the path ahead, I hoped for and succeeded in finding a thought-through, holistic and internally consistent as well as surely correct presentation of C++ in A Tour of C++, written by the inventor of and therefore a reasonable authority on C++.

What follows are my thoughts on the book A Tour of C++ [1], having begun to read it after only sporadically adjusting single lines in C++ golfs and having used it to facilitate a two thousand line C++ project [2] simulating a ficticious 32-bit architecture [3].
I am in no way affiliated with either the author Bjarne Stroustrup nor the publisher Pearson (Addison-Wesley) and purchased the book on my own.
