It is not actually the language that might be slower because you can do equal things in C and C++ that execute approximately the same speed, what matters might be overhead that some C++ constructs imply on the program. But that is only if you use such constructs... such as templates for example. Even templates can also be used in a right and wrong way. So the answer is far from being general. In good hands each tool can work wonders or be just as average as any other tool. For example: std::vector<int> abc; abc.at(0) = 1; // is slower than abc[0] = 1; // than this because of range checking In C you don't even have such constructs so there is nothing to compare it to. But if you use at() which does some additional overhead due to range checking then of course it is somewhat slower than the other version. It is like you would call more functions in C, that would execute slower due to heap/stack allocation etc. But in C++ you could as well write: char[] abc = "abc"; abc[0] = "x"; that would work equally fast in C or C++. In general, there is only one REAL issue - which of the two you find more valuable - the convenience that C++ offers over C to speedup development... or... your time.... to finish a certain project (even if it is a bit slower). Remember, programmers time is never getting more expensive it may only get cheaper.
