Smart Pointers in C++: Problems Solved, Usage, Best Practices, and Implementation Details

C++11 smart pointers—unique_ptr, shared_ptr, and weak_ptr—replace manual new/delete by providing exclusive, shared, and non‑owning ownership semantics, automatically preventing leaks and dangling references, simplifying multithreaded code, and, when used with best‑practice guidelines, avoid common pitfalls such as double deletions and cyclic dependencies.
