Can someone enlighten me on Deep Copy Problem?

I have an function in which I want to make a copy of an object.

C++ Syntax (Toggle Plain Text) 
  1. ClassBase
  2. {
  3. public:
  4. Tblk myTblk;
  5. private:
  6.  
  7. };
  8.  
  9. void ClassBase::CopyObject(const ClassBase &test)
  10. {
  11.        TblkPtr_t myTblk = TblkPtr_t(new Tblk); //TblkPtr_t is a typedef shared pointer
  12.       *myTblk = *test.myTblk;
  13. }

For some reason that doesn't work. If I use the copy constructor like this

C++ Syntax (Toggle Plain Text) 
  1. myTblk = new Tblk(*test.myTblk)

then it seems to work. I don't understand why if I dereference the pointer in my original example why it wouldn't work. Can someone enlighten me?

Your copy ctor is hiding the member variable. And even worse you have
a memory leak. 
1) Prove that the area of a circle is pi*r^2, where "r" is the radius of the circle.
