If you havent programmed in assembly language, you may be frustrated by C 's lack of certain higher - level features.

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(70)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.
