Introduced in CPP11, CPP Reference Wrapper encapsulates references for safe storage in containers like vector and list. It uses ref and cref to ensure reference semantics, avoiding unintended copies.

CPP Reference Wrapper is essential in function binding, callback registration, and custom data storage. Its ability to maintain references ensures flexibility in container-based processing and template metaprogramming.
