Improving C

[Doug Gwyn]

Another point is that correct code benefits NOT AT ALL from run-time
subcript range checking and other such aids.  How about getting the
code right in the first place instead of relying on run-time detection
of errors to find your mistakes.  (This assumes you are able to
run an exhaustive set of test cases through your code anyway, which is
a very poor assumption.)  I recommend Myers' "The Art of Software
Testing" to those who care about the subject.

Input validation is a well-known requirement.  Good COBOL programmers
do this automatically.  Is it possible that there are no good UNIX
programmers?  :-)
