Title: PROGRAMMING
IN C

Description:
C is (as K&R admit) a relatively small language, but one which (to its admirers, anyway) wears well. C's small, unambitious feature set is a real advantage: there's less to learn; there isn't excess baggage in the way when you don't need it. It can also be a disadvantage: since it doesn't do everything for you, there's a lot you have to do yourself. (Actually, this is viewed by many as an additional advantage: anything the language doesn't do for you, it doesn't dictate to you, either, so you're free to do that something however you want.)
C is sometimes referred to as a ``high-level assembly language.'' Some people think that's an insult, but it's actually a deliberate and significant aspect of the language. If you have programmed in assembly language, you'll probably find C very natural and comfortable (although if you continue to focus too heavily on machine-level details, you'll probably end up with unnecessarily nonportable programs). If you haven't programmed in assembly language, you may be frustrated by C's lack of certain higher-level features. In either case, you should understand why C was designed this way: so that seemingly-simple constructions expressed in C would not expand to arbitrarily expensive (in time or space) machine language constructions when compiled. If you write a C program simply and succinctly, it is likely to result in a succinct, efficient machine language executable. If you find that the executable program resulting from a C program is not efficient, it's probably because of something silly you did, not because of something the compiler did behind your back which you have no control over. In any case, there's no point in complaining about C's low-level flavor: C is what it is.
