Learn C in Y Minutes

This is also bad advice for C:

   void function_1();

Most people coming from other languages (like C++) will probably think that this is identical with "void function_1(void)", but without the explicit void argument list, the compiler will not warn if the function is accidentally called with parameters.

It's only an error in C++, but not in C, and the warning for this isn't included in the usual "-Wall -Wextra" set.
