Special characteristics of Constructors:
- They should be declared in the public section.
- They do not have any return type, not even void.
- They get automatically invoked when the objects are created.
- They cannot be inherited though derived class can call the base class constructor.

Characteristics of constructor functions
Constructors should be declared in the public section of the Class. Constructors cannot return values to the calling program because they do not have return types. Constructors should always be non-virtual. They are static functions and in C++ so they cannot be virtual.
What are the characteristics of constructor and destructor in C++?
Constructor is used to create the object in object oriented programming language while destructor is used to destroy the object. The constructor is a function whose name is same as the object with no return type. The name of the destructor is the name of the class preceded by tilde (~).
What is a constructor and destructor and explain its characteristics?
Constructors are special class functions which performs initialization of every object. The Compiler calls the Constructor whenever an object is created. Constructors initialize values to object members after storage is allocated to the object. Whereas, Destructor on the other hand is used to destroy the class object.
What is a constructor types of constructor?
In Java, a constructor is a block of codes similar to the method. It is called when an instance of the class is created. ... There are two types of constructors in Java: no-arg constructor, and parameterized constructor. Note: It is called constructor because it constructs the values at the time of object creation.
What is a constructor write six special characteristics of constructor?
(1) The constructor name is always same as the class name. (2) They do not have return types, not even void and therefore, they cannot return values. (3) They cannot be static or virtual. (4) They should be declared in public section. (5) They cannot be inherited though a derived class can call base class constructor.
What is a constructor in C ++? State any four special characteristics of constructor function?
Speical characteristics of constructor function :
1) The constructor name is always same as the class name. 2) They do not have return types, not even void and therefore, they cannot return values. 3) They cannot be static or virtual. 4) They should be declared in public section.
What is the difference between constructor and destructor?
Constructor helps to initialize the object of a class. Whereas destructor is used to destroy the instances.
What is destructor give an example?
A destructor is a member function that is invoked automatically when the object goes out of scope or is explicitly destroyed by a call to delete . ... For example, the destructor for class String is declared: ~String() .
What is constructor in C++ explain with example?
A constructor is a special type of member function that is called automatically when an object is created. In C++, a constructor has the same name as that of the class and it does not have a return type. For example, class Wall public: // create a constructor Wall() // code ;
What is constructor explain?
In class-based object-oriented programming, a constructor (abbreviation: ctor) is a special type of subroutine called to create an object. It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables. ... Immutable objects must be initialized in a constructor.
What is the role of a constructor in classes?
What is the role of a constructor in classes? Explanation: A constructor is used in classes to initialize data members of class in order to avoid errors/segmentation faults.
Why do we use constructor?
We use constructors to initialize the object with the default or initial state. The default values for primitives may not be what are you looking for. Another reason to use constructor is that it informs about dependencies.
