  2. Copy constructor (C++) - Wikipedia

    en.wikipedia.org/wiki/Copy_constructor_(C++)

    In the C++ programming language, a copy constructor is a special constructor for creating a new object as a copy of an existing object. Copy constructors are the standard way of copying objects in C++, as opposed to cloning , and have C++-specific nuances.

  3. Special member functions - Wikipedia

    en.wikipedia.org/wiki/Special_member_functions

    The automatically generated special member functions are: Default constructor if no other constructor is explicitly declared. Copy constructor if no move constructor and move assignment operator are explicitly declared. If a destructor is declared generation of a copy constructor is deprecated (C++11, proposal N3242 [2]).

  4. Move assignment operator - Wikipedia

    en.wikipedia.org/wiki/Move_assignment_operator

    The move assignment operator, like most C++ operators, can be overloaded. Like the copy assignment operator it is a special member function . If the move assignment operator is not explicitly defined, the compiler generates an implicit move assignment operator ( C++11 and newer) provided that copy / move constructors , copy assignment operator ...

  5. Rule of three (C++ programming) - Wikipedia

    en.wikipedia.org/wiki/Rule_of_three_(C++...

    With the advent of C++11 the rule of three can be broadened to the rule of five (also known as "the rule of the big five" [5]) as C++11 implements move semantics, [6] allowing destination objects to grab (or steal) data from temporary objects. The following example also shows the new moving members: move constructor and move assignment operator.

  6. Constructor (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Constructor_(object...

    A Copy constructor has one formal parameter that is the type of the class (the parameter may be a reference to an object). It is used to create a copy of an existing object of the same class. Even though both classes are the same, it counts as a conversion constructor. While copy constructors are usually abbreviated copy ctor or cctor, they ...

  7. Assignment operator (C++) - Wikipedia

    en.wikipedia.org/wiki/Assignment_operator_(C++)

    In the C++ programming language, the assignment operator, =, is the operator used for assignment.Like most other operators in C++, it can be overloaded.. The copy assignment operator, often just called the "assignment operator", is a special case of assignment operator where the source (right-hand side) and destination (left-hand side) are of the same class type.

  9. C++11 - Wikipedia

    en.wikipedia.org/wiki/C++11

    (However, if std::vector<T> is a C++03 version without a move constructor, then the copy constructor will be invoked with a const std::vector<T>&, incurring a significant memory allocation.) For safety reasons, some restrictions are imposed. A named variable will never be considered to be an rvalue even if it is declared as such.
