Standard Library

Sleep

std::this_thread::sleep_for(std::chrono::milliseconds(1));

Garbage Collection

Traditional C++ does not have garbage collection.
After using `new` to allocate an object, use `delete` to deallocate it.
You can also use C allocation with `malloc`, `calloc`, `alloca`, and `free`.
If using C++14, you can use shared pointers which does have automatic garbage collection.
