Why is the c++ version in the code play ground so old?

Question

?

Answer 1

how do you think old? it is just with limited features, because online codeplaygrounds can't change IDEs

Answer 2

I’ve asked questions about to_string and stoi before, the answer I got was it’s a glitch with some older compilers that should allow it.

Also SoloLearn doesn’t completely cover C++11, they left out some parts like threads.

Answer 3

It's not. It's C++11, the last major revision to the standard (C++14 and C++17 are new, not very well supported in general (especially C++17) and only add minor revisions anyway).
