Note that in C++, You do not need to use typedef as it is already typedefed to point, So you do need to use typedef for that.

An object is returned by a function. C++ calls a copy constructor to make a copy of an object in each of the above cases. If there is no copy constructor defined for the class, C++ uses the default copy constructor which copies each field, ie, makes a shallow copy. BY D Murli(India-Bhilai(C.G)) 25-6-2007 : 12:08:26 Category C++11 - Wikipedia will call the initializer list constructor, not the constructor of std::vector that takes a single size parameter and creates the vector with that size. To access the latter constructor, the user will need to use the standard constructor syntax directly. Type inference. In C++03 (and C), to use a variable, its type must be specified explicitly. Destructor (computer programming) - Wikipedia In object-oriented programming, a destructor (sometimes abbreviated dtor) is a method which is automatically invoked when the object is destroyed. It can happen when its lifetime is bound to scope and the execution leaves the scope, when it is embedded in another object whose lifetime ends, or when it was allocated dynamically and is released explicitly. C++ classes - Wikipedia A class in C++ is a user-defined type or data structure declared with keyword class that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers private, protected or public.

A copy constructor is a like a normal parameterized Constructor, but which parameter is the same class object. copy constructor uses to initialize an object using another object of the same class. Конструктор по умолчанию — это довольно простая конструкция, которая сводится к созданию для типа конструктора без параметров. Так, например, если при объявлении нестатического класса не объявить пользовательский конструктор (не важно, с параметрами или без них) C++ structs, used as small bundles of data, are often depleted of any methods. But do constructors make a struct more usable? Or do they get in the way?

При необходимости конструкторы могут получить список инициализации элемента.Constructors can optionally take a member init list. Это более эффективный способ инициализации членов класса, чем назначение значений в теле A class constructor is a special member function of a class that is executed whenever we create new objects of that class.

Constructor is the special type of member function in C++ classes, which are automatically invoked when an object is being created . Use of Constructor in C++. Suppose you are working on 100's of Person objects and the default value of a data member age is 0. Initialising all objects manually will be a very tedious task. Instead, you can define a constructor that initialises age to 0. Then, all you have to do is create a Person object and
