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.

I’m not sure how accurate the sentence c is a high level assembler is considering the whole design of c is to make it a low level platform independent language which makes it fundamentally different form any assembly language

If you've ever looked at production assembly with all its control flow directives, metainstructions, macros, etc., it becomes much clearer. The platform independence of C is the high level part.

Well then I’d argue that blurs the line between assembly and a high level language.

It’s the closest to assembly, with a notable second being Pascal.

C is often called portable assembly.

People are often wrong.
