I do not agree, this is tutorial is very specific for competitive programming and it is well known that it doesn't mean good code, e.g. https://news.ycombinator.com/item?id=9324209 https://news.ycombinator.com/item?id=9324209 and actually it was great tutorial years ago but now we have c++11 and I would like an updated version of this tutorial that use c++11 features.
