While this question seems to be a silly one, it is easiest to be prepared to. I think it worth to mention Meyers, Gamma, Coplien, Stroustrup, Schildt etc.

Smart Pointers

Smart Pointers - What, Why, Which? What are they? Smart pointers are objects that look and feel like pointers, but are smarter. What does this mean? To look and feel like pointers, smart pointers need to have the same interface that pointers do: they need to support pointer operations like dereferencing (operator *) and indirection (operator ->). An object that looks and feels like something else is called a proxy object, or just proxy. The proxy pattern and its many uses are described in the books Design Patterns and Pattern Oriented Software Architecture . To be smarter than regular pointers, smart pointers need to do things that regular pointers don't. What could these things be? Probably the most common bugs in C++ (and C) are related to pointers and memory management: dangling pointers, memory leaks, allocation failures and other joys. Having a smart pointer take care of these things can save a lot of aspirin... The simplest example of a smart pointer is aut...
