Explain the concept of constructor

Constructor is a special method of a class, which is called automatically when the instance of a class is created. It is created with the same name as the class and initializes all class members, whenever you access the class. The main features of a constructor are as follows:

• Constructors do not have any return type
• Constructors are always public
• It is not mandatory to declare a constructor; it is invoked automatically by .NET Framework.
