C++ or Pascal for an Olympiad student?

Question

C++ / C#

I would like to participate in programming olympiads (competitions). Which tool is better - Pascal or C++?
Please answer as detailed as possible.

Answer 1

C++ because there is a standard library, STL, etc. and there is no need to invent bicycles such as sorting or a hash table, which can save a lot of time. Well, if the rules are not limited.

Answer 2

Java is well suited for olympiads. Pascal has a very weak standard library. C++ is a good language and you can write efficient programs in it. However, this requires really great experience and deep knowledge of the language. It's very likely that you'll spend a lot of time fixing bugs that don't occur in Java. For example, the vast majority of ITMO Olympiads write in Java.
