Re: [Dev-C++] Memory

Ok I'm a little lost...
you can't destroy classes, only instances of classes (objects). If you 
destroy the object the memory is released - I assume by "losing memory" you 
mean memory is not deallocated i.e. made available.

does anyone know if it is possible to allocate X memory for an application 
and only let it use that much? I'm thinking that X MB of memory could be 
allocated then at the end of the program check to see if it is all available 
again.

like if ( CurrentMem == InitialMem )
     {
        cout << "Memory has been managed perfectly.";
     }
