The constructor has two parts.

    The C++ standard library instead provides a dynamic array (collection) that can be extended or reduced in its std::vector template class.

Move constructor if no copy constructor, copy assignment operator, move assignment operator and destructor are explicitly declared.

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

    Non-constant data members of classes cannot be initialized at the site of the declaration of those members. They can be initialized only in a constructor. C++11 provides solutions to all of these problems. C++11 allows constructors to call other peer constructors (termed delegation). This allows constructors to utilize another constructor's ...

In other languages (e.g. in C++) it is a constructor that can be called without having to provide ...

    One method of copying an object is the shallow copy.In that case a new object B is created, and the fields values of A are copied over to B. [3] [4] [5] This is also known as a field-by-field copy, [6] [7] [8] field-for-field copy, or field copy. [9]
