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 sequence.
Iterator to the element of the sequence in range [begin, end) is valid from the moment of initialization and until:
the moment it…
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…
Learn C++ With Collaborative C++ Development with Visual Studio Code by Julia Reid (CppCon 2020) Video
December 3, 2020
This video demonstrates how to optimize Visual Studio Code for productive open-source projects and collaborations. Programmers will learn how to work on collaborative projects while still having their own editor preferences. It showcases an in-depth exploration on C++…
Learn C++ With Back to Basics: Class Layout by Stephen Dewhurst (CppCon 2020) Video
December 2, 2020
The main function that supports data abstraction in C++ are classes. In essence, a C++ class is a C framework with additional features. This video discusses the practical way of using classes to get a better sense of different programming tasks, as many programmers often…
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 texts and letters. In C++, there is very old well-known string type (arrays of chars) and modern types…
Learn C++ With The Hidden Secrets of Move Semantics by Nicolai Josuttis (CppCon 2020) Video
November 30, 2020
A distinctive feature of C++ modern programming is Move Semantics. Although, it can also be a complex subject as it complicates the language in several cases. Experts still have a hard time with its specifics. This video talks about the hidden secrets to understand move…
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 and availability of names declarations (such as names of classes and functions) independent on template parameters are…
