This book introduces very detailed, not a learning manual, but also as a reference manual for function usage. And I also learned that the original VC6.0's MFC is not standard C , and the standard C is in 1998 to the present. VC6.0 is not very good support STL's advanced programming, but 100% supports MFC. If you want to become excellent C programmers must know STL, after all, it is now part of standard C , using STL does not need to create arrays, linked lists, and some common data structures.
But I think it is like learning API using STL, or follows others, so I still don't learn how to use STL, today is mainly understanding.
