A couple of words about TDD
Unit-test coding supposes to be one of the most significant methodological achievements of the industry, let’s say, for about last 15 years. The Internet is full of enthusiastic exclamations [1, 5, 6]. However, there are some not so enthusiastic ones or even without any enthusiasm at all [2, 3, 13]. A humble attempt to consider pluses and minuses of TDD (test driven development) based on literature research and some practice is being made in this article. At the beginning, it’s necessarily to clarify the terminology because there is some misunderstanding: saying TDD one means one thing and another one means ...

Metrics - LoC
This is going to be a small set of articles devoted to metrics. The first one is about LoC - Line of Code. I think that the first reaction on that phrase is smile. Many of us have heard about an anecdotal case at Macintosh when they tried to count the lines of code and measure productivity. There is even a classic saying of Kenneth Thompson: "One of my most productive days was throwing away 1000 lines of code". Actually, counting SLOC is routine and boring: we simply carefully count the lines one by one including code lines itself, comments ...

Metric - Cyclomatic Complexity
There is a simple and logic explanation: the more “if”, “while”, “for”, and etc. in code the higher the complexity of the code improvement, management, understandability and refactoring. Cyclomatic (here and on – V(g)) is an a-posteriori metric, the same as LOC. V(g) is being used only after the initial code is written. Some programmers criticise these things saying that better to prevent too complicated code than correct it afterwards. However, in real life very often we have the situation when the code is already written by somebody else and according to the Murphy Law *you* have to deal with ...

SESE vs SEME
SESE/SEME are terms of structural programming and were introduced at 80-s. Nothing new. However, experience shows that some programmers do not know about them till today. That’s why it makes sense to explain what it is all about. I want to express my gratitude to Ruslan, Oleg, and Alex who actively helped me to work this theme out. SESE = Single Entry Single Exit. SEME = Single Entry Multiple Exits. It is very simple: any function has a single entry but one or many exits. Consider this code as an example:

How to use ASSERT
Asserts can be very helpful in any development… If you use them wise. Alas, in the net there is miserable information about how to use these wonderful tools of security programming correctly. The only more or less understandable explanation that I have found is Code Complete by Steve McConnell. However, I hope this article, as minimum, will not be worse. Definition Assertion is a macros that is used in software and which helps a developer to check if a program is being implemented correctly, especially at certain places of code. Assert forces the program to end the work instantly. Like ...

.h/.hpp including strategy
Sorry to say but people are very thoughtless concerning filling up of .h-files. Often you can see just a huge dumping site of everything imaginable there. This article is devoted to classify the approach of working with .h-files. It is a result of my conversations with Anton, who I truly believe, is the best one among C++ers which I have ever seen. Globally, there are two ways of including into .c/.cpp-files. umbrella header fine grained headers A couple of examples: 1) ntddk.h, windows.h. Let’s assume we have foo.h, which in its turn has ntddk.h and other odds and ends, and ...

How to walk through a container
Just a small article explaining how to work with the STL containers. Vector is taken as an example. Аt the beginning I would like to say thanks to Anton. The reason for this article is multiple examples of incorrect iteration seen everywhere in Internet:
