View all tagsstd::shared_ptr
Smart pointer with shared ownership via reference counting. Multiple shared_ptrs can own the same object, deleted when last owner destroyed.
std::unique_ptr
Smart pointer with exclusive ownership. Zero overhead, automatic cleanup, move-only semantics. The default choice for dynamic memory.
std::weak_ptr
Non-owning observer of shared_ptr-managed objects. Doesn't increase reference count, enables checking if object still exists.
