C++ is a strong and faster programming language, this feature really important on dynamic operations running less than in milliseconds of intervals. C++ is one of the best to analyze video camera images, it is good to analyze video image operations by using very modern…
Learn C++ With A Physical Units Library For The Next C++ by Mateusz Pusz (CPPCon 2020) Video
December 9, 2020
“MP-units’ is a library that is proposed for C++ standardization. This video should get the audience acquainted and be familiar with its most significant principles, structure, and features. Mateusz illustrates code samples in his discussion on how the ‘mp-units’…
In this article we will add some quick methods to show how to use basic components in C++ Builder. Most of component properties and methods are same in VCL and FMX projects. If you are a beginner we highly recommend you to watch this Introduction To C++ Windows Development With C++Builder video to understand C++ Builder / RAD Studio IDE interface and some basic mechanisms. This video will help…
Learn C++ With Back to Basics: Templates by Andreas Fertig (CPPCon 2020) Video
December 7, 2020
This video introduces what generic programming is, along with the different kinds of functions, namely: function, class, and method templates. After tackling the basics, this will help you keep in mind that codes should not be all about the templates. This is mostly for the…
Let’s slightly modify the example from The Move Iterator Adapter in C++ post:
#include
#include
#include
#include
/// @warning BUG! PLEASE, DON'T USE!
auto deep_copy_to_list(const std::vector& src)
{
std::list dst; // constructs the empty list
copy(cbegin(src), cend(src), begin(dst)); // cause memory corruption (if !src.empty())!
return dst;
}
In the example above the object of…
The dereference prefix operator * being applied to iterator returns the lvalue reference to the element pointed by the iterator. Therefore, algorithms such as std::copy or std::transform calls copying constructors of processed elements, for example:
#include
#include…
By using bidirectional iterator or random access iterator (see Iterator Categories in C++) it’s possible to traverse the sequence in backward direction by using operator -- or by using the special adapter template class std::reverse_iterator. But why to bother with reverse…
