Looks more like old-school C to me, although the variable names are a bit too long for a real C programmer :)

(but I don't know whether C already had the "const" keyword at that time)

It is C. Otherwise, they would have used `<cstdio>` or `<iostream>` rather than `"stdio.h"`

However, it is written in the common parts of the languages, so it will compile under either gcc as a C file or g++ as a cpp file just fine without changes.

stdio.h works just fine in C++.

Yes, I meant only that if it was foremost intended to be C++, one might expect one of the more idiomatic i/o libraries to be used.

Depends on when you started writing C++. C++98 has left its mark on some of us and muscle memory is a thing.

It did, "const" exists since C89.
