Cool discussion, though this a much later issue for
most coders, let alone those just starting to learn C.

Random link:

One part of programming that could use a lot more effort is writing 
readable code, so that it actually makes sense to someone not familiar 
with it. (Or one self, a week later.) Choosing descriptive names for 
variables as opposed to names 1 or 2 chars long does a lot for 
readability. (Not meant as criticism of any code shared here.)

Another random link:
"Best practices for programming in C"

Another one:  
"Comments on Comments"

BTW, do long/short variable names matter at all for performance in C 
and C++? And what about function- and class method names?
