|Picking up the Bible (K&R) and quoting without permission from page 17

We're going to be that way, hmm?

|Any single character can be written between single quotes, to produce

Instead of quoting points that say nothing, why not take a look a bit
further down on the page:

"You should note carefully that '\n' is a single character, and in
expressions is equivalent to a single integer; ..."

|and page 35 says
|
|A {\it character constant\/} is a single character written within
|single quotes, as in 'x'.

as well as:

"Character constants participate in numeric operations just as any
other numbers, although they are most often used in comparisons with
other characters."

It's not clear that you are refuting my references above, although you
have certainly left out of your quotations the relevant points.
