I don't have a copy of this book. Are you sure it expects a 4-digit
year? Putting a 20 in front of a 2-digit year would only be valid in
that case. It also limits the function to years 2000-2099, hardly a
modern approach. 

I also question the lack of a default case in the second switch block.
This is a serious deficiency in a tutorial that is supposed to be
demonstrating "a modern approach" to C. 

Is there an online version of this example?

It appears to be K.N. King, "C Programming : A Modern Approach" page
89.
