Constructor and Destructor

Types of Constructors in C++. Constructors are of three types: 1. Default Constructor. 2. Parametrized Constructor. 3. Copy COnstructor.

Literals for user-defined types

18 sept. 2003 C++ does not provide a way of defining literals for user-defined types. Instead constructors are used. For example: 15. // int literal.

2 3 Constructors A constructor is a special function that initializes the state of the object; it has the same name as the class but does not have a return type There can be more than one constructor Note that the compiler will provide a default no-argument constructor if none is coded Some constructor is always executed when an object is

All classes have a default copy constructor assignment operator and destructor which perform the corresponding operations on each data member and each base class as shown above There is also a default no-argument constructor (required to create arrays) if the class has no constructors Constructors assignment and destructors do not inherit

• Member initializer Lists

  A constructor can optionally have a member initializer list, which initializes class members before the constructor body runs. (A member initializer list isn't the same thing as an initializer list of type std::initializer_list .) Prefer member initializer lists over assigning values in the body of the constructor. A member initializer list direc...

• Default Constructors

  Default constructorstypically have no parameters, but they can have parameters with default values. Default constructors are one of the special member functions. If no constructors are declared in a class, the compiler provides an implicit inlinedefault constructor. If you rely on an implicit default constructor, be sure to initialize members in th...

• Copy Constructors

  A copy constructorinitializes an object by copying the member values from an object of the same type. If your class members are all simple types such as scalar values, the compiler-generated copy constructor is sufficient and you don't need to define your own. If your class requires more complex initialization, then you need to implement a custom c...

• Move Constructors

  A move constructoris a special member function that moves ownership of an existing object's data to a new variable without copying the original data. It takes an rvalue reference as its first parameter, and any later parameters must have default values. Move constructors can significantly increase your program's efficiency when passing around large...

• Explicitly Defaulted and Deleted Constructors

  You can explicitly default copy constructors, default constructors, move constructors, copy assignment operators, move assignment operators, and destructors. You can explicitly deleteall of the special member functions. For more information, see Explicitly Defaulted and Deleted Functions.

• constexpr Constructors

  A constructor may be declared as constexprif 1. it's either declared as defaulted or else it satisfies all the conditions for constexpr functionsin general; 2. the class has no virtual base classes; 3. each of the parameters is a literal type; 4. the body isn't a function try-block; 5. all non-static data members and base class subobjects are initi...

• initializer List Constructors

  If a constructor takes a std::initializer_list as its parameter, and any other parameters have default arguments, that constructor is selected in overload resolution when the class is instantiated through direct initialization. You can use the initializer_list to initialize any member that can accept it. For example, assume the Box class (shown ...

• Explicit Constructors

  If a class has a constructor with a single parameter, or if all parameters except one have a default value, the parameter type can be implicitly converted to the class type. For example, if the Boxclass has a constructor like this: It's possible to initialize a Box like this: Or pass an int to a function that takes a Box: Such conversions can be us...

• Order of Construction

  A constructor performs its work in this order: 1. It calls base class and member constructors in the order of declaration. 2. If the class is derived from virtual base classes, it initializes the object's virtual base pointers. 3. If the class has or inherits virtual functions, it initializes the object's virtual function pointers. Virtual function...
