I am going to start my preparation in Competitive Programming. I know some basic C++ (printing, loops, if and else statements).
I feel I need to study a bit more advanced C++ things like structs, memset, pointers, iterators and all. Can someone give a nice place to learn these stuff from ? (I’m preparing for INOI so if anyone can tell me things related to it, I’d be happy.)
I am confused as to what book to use for CP :- I have CP3 Book by Steven and Felix Halim and I also have Competitive Programmer’s handbook by Antti Laaksonen. Which one should I use?
Once I read a chapter in either of these books, which website (Codeforces, SPOJ,etc.) has good problems to solve ? I’d prefer Codeforces, so can anyone tell me if a beginner can practice in Codeforces.
