      What is a Destructor and Constructor?


    • #53046

      Destructor:

      A destructor is a member function which destructs or deletes an object.

      When is destructor called?

      A destructor function is called automatically when the object leaves scope:

      (1) the function ends
      (2) the program ends
      (3) a block containing local variables ends
      (4) a delete operator is called

      Guidelines of destructor:

      1) Destructors have the same name from the class gone before by a tilde (~)
      2) Destructors don’t take any argument and don’t return anything.

      Constructor:

      1) A constructor is an uncommon type of member function that introduces an object automatically when it is created.

      2) The compiler identifies a given member function is a constructor by its name and the return type.

      3) A constructor has the same name from that of the class and it doesn’t have any return type.
