Question

Mention the differences between constructor and destructor.

Answer 1

Constructor:

• The name of the constructor must be the same as that of the class.
• No return type can be specified for the constructor.
• A constructor can have a parameter list.
• The constructor function can be overloaded.
• They cannot be inherited but a derived class can call the base class constructor.
• The compiler generates a constructor, in the absence of a user-defined constructor.

Destructor:

• The destructor has the same name as that of the class prefixed by the tilde character
• It has no return type.
• The destructor cannot have arguments
• Destructors cannot be overloaded i.e., there can be only one destructor in a class.
• They cannot be inherited.
• In the absence of a user-defined destructor, it is generated by the compiler.
