# C++ `std::shared_ptr` partial implementation ## The what C++ has something called `std::shared_ptr` as a part of the standard library. I implemented a subset of the functionality present in `std::shared_ptr` for a class I took in college. What `std::shared_ptr` does is that it holds a pointer to something on the heap and a counter to track how many `std::shared_ptr`s for that pointer exist, when that number hits 0 the pointer is freed. Compared to manually needing to keep track of whether anything is using a pointer it's reasonably nice. ## What was learned I shouldn't procrastinate.
