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…
The importance of testing can never be underestimated. Although sometimes, writing tests can be difficult and can be a little time-consuming. But there are other ways to make testing easier, like writing tests first. This video will give you insights on how to get you…
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 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…
