What are destructors

Question

any relation with constructors

Answer 1

Constructors are called when an object is created. Destructors are called when an object is deleted.

Answer 2

They're comparable to constructors. While constructors instantiate objects, destructors delete them to free memory.
In both cases, you can add code to perform extra actions before instantiation/deletion. Ex: Closing files and databases, writing to a log file, etc.
An object is deleted when it leaves its scope. Ex: If you make an object in a method, that object is deleted after the method ends.

Answer 3

Destructors are nothing but what destroys the scope of an object once it is no longer needed.

Answer 4

Answer 5

constructor = created
destructor = deleted
