Once dissambled, binaries of the C code compiled with gcc and g++ are exactly the same, so they probably run at the same speed. The C++ code produces mode machine instructions than the C code, so it probably takes more time to run than its C equivalent.
I'm not an expert, and this exercice is probably bogus.
I don't want to compare performance speed between C and C++, just wanted to note that (on Windows) Intel's C (and C++) compiler sometimes produces binaries that are 3 or 4 times the size of MS VC++ compiled binaries! On the other hand they need _less_ CPU and/or _less_ memory to execute. Bigger binaries do _not_ necessarily mean slower execution speeds...
