There are few points about it: 0. shared_ptr is a smart pointer which can share the ownership of object (managed object). 1. Several shared_ptr can point to the same object (managed object). 2. It keep a reference count to maintain how many shared_ptr are pointing to the same object. and once last shared_ptr goes out of scope then the managed object gets deleted. 3. shared_ptr is threads safe and not thread safe. [what is this??] a. control block is thread safe b. managed object is not 4. There are three ways shared_ptr will destroyed managed object. a. If the last shared_ptr goes out of scope. b. If you initialize shared_ptr with some other shared_ptr. c. If you reset shared_ptr. 5. Reference count doesn't work when we use reference or pointer of shared_ptr. #shared_ptr #smartPointer #CppNuts
