  I found an example in the CppCoreGuidelines that is surprisingly similar to the example in my article: https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#cp42-dont-wait-without-a-condition

• The order of pointers/variables declared in member function, unfortunately, matters.

  Take a look at https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md

• JUST FINISHED MY FIRST PROJECT, VIEW BELOW...

  Personally, I use gsl::index from the Guidelines Support Library (for the C++ Core Guidelines, which is an alias for std::ptrdiff_t.

• Why do default parameters in virtual functions not follow dynamic dispatch?
  reddit.com/r/cpp_questions | 2021-05-05

  I don't know if it's worth complicating the feature just for this. You also have the extra overhead to consider. To stay true for the phrase "don't pay for what you don't use" maybe you would have to opt-in to this behaviour (virtual default arguments?) If it's only for virtual functions it might be acceptable because people don't normally use default arguments with virtual functions, but if you want default arguments to work for function pointers as well it would incur an overhead to all functions and many people would find that unacceptable.

• C++ Concepts and logical operators

  Not using negations directly, but putting expressions into named concepts seems to go against the rule of using standard concepts whenever possible instead of writing our own concepts. But due to the subsumption rules, this is necessary.

• C++ Constructors, Memory, and Lifetimes

  As you are officially discouraged to use new and delete directly (https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines...) and I fully agree with this guideline, I was disappointed to see new being mentioned so early and not immediately being followed up with std::unique_ptr and std::shared_ptr. Especially because you introduced the constructor/destructor subsection with how destructors can be used to free memory. A general mention of std::shared_ptr would have been expected as well, I think. This seems like a worthwhile resource for beginners, so it's all the more unfortunate that it is behind on showing modern C++. Generally I feel like a big issue of the language is that most learning resources are not representative of how good, modern C++ should look and therefore safety and general development experience suffers.

• What type should be used for sizes and subscripts?
  reddit.com/r/cpp_questions | 2021-05-02

  Also, the C++ Core Guidelines suggest gsl::index.

• Lambda functions

  Another use for lambdas is complex initialization (ES.28 on the C++ core guidelines).

• Our teacher sure is a good teacher.

  Or that in modern C++ using new and delete directly is discouraged. You are supposed to either use stack variables, smart pointers or have a container handle the lifetime of objects for you.

  Once you accommodate yourself with modern c++ those official guidelines made by iso committee are super helpful: https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines

• Modern C++ Won't Save Us (2019)

  https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines For new code stick to the core guidelines to make life much easier. I think c++ is imperfect, but it is de facto the best/fastest/most-powerful language in existence right now.
