Part 1
Identify targets in the Memefighter codebase from Intermediate c++ for resource sharing, implement the sharing with std::shared_ptr, and consider/discuss potential downsides to the resource sharing for each instance of resource sharing. Solution can be found here.
Part 2
Make a simple announcing class, and then use allocate_shared in conjunction with LocalAlloc from Win32 to create an instance of that class that is managed by a shared_ptr with a monolithic control block.
