FWIW, the proper way to include standard C headers
in C++ is without .h, and a prepended "c".  So that would be
#include <cstdlib>.

C++ forbids functions which are not prototyped, so
void is useless here, and () cannot mean "I did not
specify the argument types".  So it's rather more
common not to use void for incoming arguments than
specifying it.
