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…
If you are on the hunt for the best C/C++ compilers available today, this article lists the top C/C++ compilers for Windows with their features. It’s very hard, in fact, to identify which C++ compiler is the best for you, as this is mostly about what you want to achieve with your code. If you want to implement small projects for analysis and calculations without GUIs and many other features…
An integrated development environment (IDE) is a software application that provides a complete set of features for application development. Code is generally written in text format, and you can easily edit or modify your code using text editors like Notepad, Word, Wordpad…
Learn The Initialization Of Class Objects By Rvalues When Building Windows Apps In C++
November 25, 2020
C++Builder includes the use of rvalue references, which allow creating a reference to temporaries. When you initialize to an class object using an rvalue(a temporary object), C++11 looks to see if you have defined a move constructor in your class. If you have, the temporary…
Learn About Using Right Angle Brackets In This C++11 Feature For Windows Development
November 25, 2020
In the Clang-enhanced C++ compilers, two consecutive right angle brackets no longer generate an error, and these constructions are treated according to the C++11 standard.
C++03’s parser defines “>>” as the right shift operator or stream extraction operator in all cases. However, with nested template declarations, there is a tendency for the programmer to neglect to place a…
