Greetings

Well - - - - enmasse there was a declaration of 'learn C (my son!!)'.

So I'm trying to work my way through the book "learning Gnu C".

Chapter 3 first exercise 1 is here:
https://www.nongnu.org/c-prog-book/online/c355.html#AEN369

except whether I type in the code or copy and paste it - - - - well the
compiler pukes out

>$ gcc -Wall -o bicycles.c
>gcc: fatal error: no input files
>compilation terminated.

so has something changed?

(Book is from the early 2000s maybe things have changed - - - - ??????????)

Please advise
