Thanx guy for the usefull discussion of my proposal (~main())
I understood that there are another mechanisms to deallocate
globals and from the other hand ~main() is useless because
main() is not a only 'constructor' of program instance, but
it has a code, which is aimed to run something after starting.
Beside that realization of ~main() will be incompatible
with plain C language. The more proper way is to create
application instance class or at least to use atexit()

Thanx

Hi all!

All we know that in c and c++ languages every program must have a program
startup function - main() (sometimes it called as WinMain(), LibMain(), etc)
In terms of OOP main() functions is a kind of constructor of program instant.
If there is constructor must exist and destructor! In other words function
~main() - destructor of program instant. main() and ~main() are the places,
for instance, for allocation and freeing global arrays or initialization
and deleting static members of classes:

class A
  {
  ....
  public:
    static char *s_lpch;
  public:
    A();
    ~A();
  ....
  };

main()
  {
  ...
  A::s_lpch=new char[128];
  ...
  }

~main()
  {
  ...
  delete [] A::s_lpch;
  ...
  }

I'm not a specialist in computer languages, I'm programmer, more or
less experienced in C and C++. I think that realization of such
proposal is quite possible (~main() function as part of C++ standard
feature).
I wonder what is the opinion of specialists (and non-specialists too)
on this matter?

Seems totally unnecessary and not very logical:

main() is not a constructor, main is not a classname,
why would anyone want a ~main()?

main actually has code.  If you use new in main, use delete in main
when you are done.

If you really want, create an Application class (MFC does it).
