CPP Smart Pointers

Introduced in CPP11, CPP Smart Pointers manage dynamic memory automatically, reducing the risk of memory leaks. Common types include shared_ptr, unique_ptr, and weak_ptr. They automatically release memory when no longer needed, supporting resource management.

CPP Smart Pointers simplify memory management while enabling features like reference counting and ownership transfer. They integrate seamlessly with other CPP Standard Library components, enhancing memory safety and reliability.

CPP Smart Pointers Equivalents: Compare and Contrast

CPP Smart Pointers provide automated memory management and are part of the CPP STL. They include `std::unique_ptr` (for exclusive ownership), `std::shared_ptr` (for shared ownership), and `std::weak_ptr` (for non-owning references). These tools help prevent memory leaks and dangling pointers in complex programs. Below is a detailed comparison of their equivalents in various programming languages.
