Answer 2

Neither of these are not required by a class.



Constructors: Used to initialize a class, including allocating memory or opening files (i.e. log files) if necessary, and setting default values for member variables. There can be zero (0) to many constructors for a class.



Destructors: Used to uninitialize a class, which includes deallocating memory as necessary, closing files that may have been opened by the class, etc. There can be only one deconstructor.

Answer 3

No.

=

Constructors and deconstructors are in c++.

The main use of constructors is to initialize objects.

The main use of destructors is to release dynamic allocated memory.
