Very interesting, that printf has that big impact on execution of standard programs. Printf is very powerful (and one of the reasons for the success of C -- for example when you compare it with the standard library existing in Modula 2 or (old) standard Pascal), but that power also comes with a cost.<p>It would be interesting, how the situation is in C++ with its newer stream based output, that is more based on compiler support (as much I know). Does anybody have experiences with it?
