What is the purpose of using a destructor in C++?
To take care of garbage collection in c++
it is a standard to have destructor in every class, though the use is not much.
if we want to delete an object using delete operator, then that class should have destructor, else it gives compile time error.
if your class contains constructor to initialize some variables then it is mandatory to have destructor also.
The main purpose of destructor is to free all the resources which you have allocated during your object's life time. Example: Freeing resources like memory allocations, opened files, opened sockets, database connections, resource locks etc..)
