Why some OJs don't update their compilers?
By Pluteum, history, 3 years ago, In English

Codeforces is one of the few platforms which support C++20. Some others are using C++17 like AtCoder and CodeChef. Topcoder and many classical OJ such as HDU is still using C++11 if I recall correctly. POJ is even on C++98... And for Java I haven't seen one that supports Java18.

So here's the question. I think update the compilers is rather a simple thing. Well, at least for my PC. Is there any technical issue on updating the compilers or will it cause some trouble?

Sorry, I don't have many knowledge on this, but it really confused me because it makes me to follow different standard when solving problems on different OJ...

POJ is on C++98 (!?). I think there's a quite a few older judges that are too. I don't mind even C++11, but any older than that and I usually don't bother with the platform, there's just too many QOL features missing for me to enjoy it.
