Should I use smart pointers at all and forget about classic normal pointers?

I have been using C ++ for a long time and I know very well about caution when allocating and freeing memory, especially not forgetting to delete unused instances.

Now, I just recently used boost and with the problem I am facing, I am forced to use smart pointers (in particular, shared_ptr). So, if I am going to use shared_ptr for this problem, should I use smart pointers to my entire normal code base of pointers?

  • Smart pointers have overhead. On desktop applications this is usually not a concern, but depending on what you do, it may be.
  • Smart pointers will not work correctly if you have reference loops, i.e. A pointing to B and B pointing to A, or even something that points to itself.
