Which is faster between C and C++?

Answer 1

Just because C++ is higher level than C doesn't make it slower. In fact, C++ was designed to be faster (if not just as fast as) C. There are a few cases and arguments which may benefit your evaluation:

Answer 2

In my opinion, C would have a bit faster. Because it have less function than C++.

Answer 3

Both have the same speed.

Answer 4

Their speed is quite similar *but* using C++ classes and other object-oriented features is slower than C. If you're going to only use normal types, functions, C-style arrays, the C standard library etc. (basically if you're going to write code that's valid in both languages, which most C code is) compiling it using a C compiler will make it faster (though not by much) and make the executable smaller.
