There is indeed so much crap in print !

Here is some palatable food for thought I would recommend :
- The C programming language, 2nd edition (Kernighan and Ritchie)
- The practice of Programming (Kernighan and Pike)
- C traps and Pitfalls (Andrew Koenig)
- The C puzzle book (Alan R. Feuer)
- Expert C Programming (Peter Van der Linden)

As a rule of thumb, stay away from books more than an inch thick or using
more than 4 colors on the cover.

the proper prototype for main is
int main(int argc, char **argv);
or possibly :
int main(int argc, char *argv[]);
which is semantically equivalent, but emphasises the fact that argv points
to an array of char*

The mere fact that you do not use the arguments doesn't justify a change of
prototypes. It may even become a portability issue in some circumstances.

Glad to help.
