This semester I have data structure class, my professor Aldo Von Wangenheim, decided to use C in the first part of the class, and in the end C++. If you don't know it, he recommended this C course. He asked us to solve some exercices. Me and my colleague solved it and I'm uploading it here.
PS: I start translating "all" old posts. Maybe this old ones, don't have all stuffs translated (like attachments in this one)
