pointertraits
Pointer_traits is a standard library facility in C++ that provides a uniform interface for pointer-like types. Its primary purpose is to enable generic code to treat raw pointers and smart pointers in a consistent way, exposing common type information and utilities without requiring knowledge of a specific pointer implementation. The template is defined in the standard library header <iterator> and is often used in template code that must work with multiple pointer abstractions.
The core idea of pointer_traits is to describe the characteristics of a pointer-like type through a set
Pointer_traits is specialized for raw pointers as well as for user-defined pointer types that meet the required
Typical usage involves extracting element_type for type traits, constructing or converting pointers in a generic way,
