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…
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…
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…
auto-typed variables is a C++11 feature that allows the programmer to declare a variable of type auto, the type itself being deduced from the variable’s initializer expression. The auto keyword is treated as a simple type specifier (that can be used with * and &), and its semantics are deduced from the initializer expression.
auto-typed Variables Examples
int IntFnc() {}
bool…
Learn About Using C++ rvalue References In The C++Builder BCC32 Compiler
October 31, 2020
BCC32, which is the classic C++Builder 32 bit compiler, includes the use of rvalue references, which allow creating a reference to temporaries. Also, rvalue references avoid unnecessary copying and make possible perfect forwarding functions. This feature is one of the C++11…
