pros and cons of smart pointers

Question

I came to know that smart pointer is used for resource management and supports RAII.

But what are the corner cases in which smart pointer doesn\'t seem smart and things

Answer 1

Raymond Chen is notoriously ambivalent about smart pointers. There are issues about when the destructor actually runs (please note, the destructor runs at a well-defined time in a well-defined order; it's just that once in a while you'll forget that it's after the last line in your function).

Also remember that "smart pointer" is a pretty big category. I include std::vector in that category (a std::vector is essentially a smart array).
