From SGI’s STL documentation:
Regardless of the fact that the
std::setis containing pointers or any other types, this erases an element from the set. If your pointer is pointing to a dynamically allocated object/array, you must remember todelete/delete[]it after erasing it from the set (which shouldn’t be a problem, since you already have the pointer)
