Mais oui, je parle français, moi aussi!

One uses the C standard library and the other the C++ standard library
to produce the same result. How can you call that *triché*?

Anyway, GCC is capable of taking the same C code and producing in C++
mode what seems to be exactly the same object:

~ $ cp hello.c hello3.cc
~ $ cat hello3.cc
#include <stdio.h>

int main(void)
{
  puts("Hello world!");
}
~ $ c++ -o hello3 hello3.cc
~ $ ./hello3
Hello world!
~ $ ls -l hello3
-rwxr-xr-x 1 alwyn alwyn 11548 3 Oct 22:36 hello3
~ $
