Is it necessary free memory allocated for member of structure, like in C? I
suppose not (we have gc). Example:
struct BITMAP {

ubyte[] pixels;

BITMAP* bitmap = new BITMAP;
bitmap.pixels = new ubyte[100*100];

// delete bitmap.pixels; //not necessary?
delete bitmap;
No, you don't need to manually delete pixels, but also not the pointer.
By the way, structs are constructed on the stack; only by using 'new' will it
be on the heap, but you often don't need that. Conversely, if you want truely
referenced and heap-allocated objects, you may want to use class instead of struct.
A common exception may be for data structures made of possibly numerous
"pointed" objects, such as linked lists or trees of struct nodes. There, you
may want manually pointed struct objects.
