Hi,

I've recently been working my way through K&R (second edition) and whilst
most of it is clear enough, I'm having trouble with 5.11, 5.12 (Pointers to
Functions, Complicated Declarations) and I thought I'd ask here to see
if anyone can help.  The main thing which is puzzling me, is just why
you'd want to create a pointer to a function?  Another thing is that looking
at the sort program in 5.11, there is a reference to a function called
"comp", but I can't actually see any function called "comp" anywhere in
the code?  I'd also appreciate it if anyone could direct me to any more
sources of information on the topics covered in 5.11 and 5.12.

Thanks in advance for any help,

Lloyd
