Quick Q: insert vs emplace vs operator[] in c++ map
Quick A: the difference is in the performance and the behaviour in case an element is not already inserted.
Recently on SO:
insert vs emplace vs operator[] in c++ map
In the particular case of a map the old options were only two: operator[] and insert (different flavors of insert). So I will start explaining those...
Expressiveness, Nullable Types, and Composition (Part 1)
How do you do it?
Expressiveness, Nullable Types, and Composition (Part 1)
by Rafael Varago
From the article:
We’re software developers, our mission is to provide software that solves problems. And in its essence, writing software is all about composition.
We have a big problem to solve, so we break it up into smaller pieces that can be more easily comprehended, and then we compose these smaller pieces together into working software...
The Regular Expression Library--Rainer Grimm
A quick introduction.
The Regular Expression Library
by Rainer Grimm
From the article:
My original plan was it to write about the rules of the C++ Core Guidelines to the regex and chrono library, but besides the subsection title, there is no content available. I already wrote a few posts about time functionality. So I'm done. Today, I fill the gap and write about the regex library.
ReSharper C++: Better Ways to Test C++ with doctest
doctest stands out with its ability to write tests in a new and easier way, unlocking the potential for more thorough, up-to-date, and uniform testing.
ReSharper C++: Better Ways to Test C++ with doctest
by Viktor Kirilov
From the article:
What truly sets doctest apart is the ability to use it alongside your production code. This is made possible because of 5 main properties:
- lightning speed of compilation - see the benchmarks
- ability to remove everything testing-related from binaries for final production builds by defining a global preprocessor identifier
- easy integration with the main() function of applications - supporting 3 scenarios: only tests, only the program, and both
- ability to write tests across multiple shared objects and have them registered in a single place for uniform reporting
- transparency - no warnings or other artifacts
Going a step further – doctest can even be used as a general-purpose assert library within the production code itself - outside of a testing context!
Here is a direct question/answer thread of a user interested in mixing production code and tests.

General stability and performance improvements, i.e., in our Constificator beta plug-in, for making your code more const correct.
A new technology for C++ -- Erkam Murat Bozkurt
In this article, a new programming technology for C++ has been introduced.
A new technology for C++ and its application to the multithreading
by Erkam Murat Bozkurt
From the article:
This technology acts as a separate intelligent actor simplifying software development process. In fact, this technology is a new meta-programming system which builds application specific libraries for its users. The tools that are built on the library construction process collect status information from the process and act as autonomous process management systems. This new programming technology may offer a good alternative for interpreters that are used on high level languages.
Yuri Minaev - Don’t take on C++ programmers support
It's a kind of humorous talk about the life of a development team which also deals with supporting C and C++ programmers. Actually, working with programmers is a lot of fun, and it is very productive. Not only can they send you a memory dump, but sometimes even partially solve the problem themselves and give you a hint. However, there's a flip side. If they have a technical issue, be ready to consume pints of coffee and loads of cookies. I shall tell you about our interesting and funny experience related to technical support of the PVS-Studio analyser - for example, how the tool goes nuts when coming across a 26mb string literal.
