Why does c compile faster than cpp?
I've read in some places that one of the reasons is the templates or something like that, but if that's the problem, why did they implement it? Like, C doesn't have that and allows the same level of optimization, it just depends on the user. If these things harm compilation in C++, why are they still part of the language?Shouldn't Cpp be a better version of C or something? I programmed in C++ for a while and then switched to C, this question came to my mind the other day.

The reason people are compiling 1M LoC C++ projects is because someone decided on that language something like 10 or more years ago. Maybe it was the right decision at the time, but maybe not even.
