A. Smart pointers
Answer: Smart pointers
Smart pointers are library types that help manage dynamically allocated objects automatically.
Common smart pointers include unique_ptr, shared_ptr and weak_ptr.
They work with object lifetime and RAII, reducing the need for manually writing delete and helping prevent common memory-management problems.
