For compatibility reason to C the C++ language include the union construct which allows to manipulate several different types in a uniform manner. The reason I’m writing that this feature exist for compatibility reasons is that is almost completely useless when you’re doing object oriented programming, the only allowed types to be used with union are POD’s, non […]

The only good news from this 2016 is that […]

About C++
When someone tell me that he know’s C++ and that he actually is a C++ programmer I believe him, but, this statement need some further explanation about which version of C++ the fellas is talking about!. Most C++ programmers knows C++03, eventually a little of C++11 and that’s all. Nowadays the tag C++ is used by […]
Stern-Brocot tree’s.
I’ve encountered this mirable structure this weekend when dealing with cleaver ways to represent fraction of rational numbers n/m where gcd(n,m)=1 (nominator and denominator are relatively prime), Stern-Brocot tree’s are just all about building all the possible fractions that are in they lowest form. What’s interesting (but that came as evident once one understand this structure) is […]

C++17: Folding expression.
That is one of those new additions to the language that for the most part is not understood, but that’s not a surprise since most of the people do not understand as well for what reason on heart someone included something diabolic as the variadics in the C++ language. The folding expressions was added to the […]

C++17: map splicing
Std::list have a very useful operation which allows you to move elements from one list to another, it’s called splicing. Splicing come’s almost for free, no elements are really moved but only the pointers internally used by std::list are copied from one container to another. Here’s how splicing work: The first invocation of the splice function […]
