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…
Let’s slightly modify the example from The Move Iterator Adapter in C++ post:
#include <algorithm>
#include <list>
#include <string>
#include <vector>
/// @warning BUG! PLEASE, DON'T USE!
auto deep_copy_to_list(const…
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…
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 iterators if the operator -- is available for iterators with bidirectional traversing capabilities? The answer is…
Conceptually, iterators are consists of five categories:
input iterator is intended to traverse sequences in the forward direction and provides the read access to the pointed sequence element;output iterator is intended to traverse sequences in the forward direction and…
Iterator abstracts the concept of pointer to the sequence in range [begin, end), and thus provides the following basic operations:
dereference to obtain the current element;movement to point the next element;comparison to determine at least the end of…
There are a lot ways to operate on files in C and C++. In C programming is enough to use FILE, fopen(), fclose() operations. In C++ FileOpen().was enough to operate before. In Modern C++ because of multiplatform operating systems, global languages and for the other benefits of usage File Streams are better to operate better and more friendly. There is a good information about Using File Streams…
In programming, one of the most used variables is text strings, and they are sometimes really important when storing and retrieving valuable data. It is important to store your data safely in its language and localization. Most programming languages have issues when storing…
In order to compile C++ templates the compilers like Embarcadero RAD Studio C++ compilers are required to perform two stages: definition stage and instantiation stage.
The template definition stage
On this stage the following checks are performed:
static assertions…
