If you really have a problem with using *p
then you should use p[0]. Never, never 
underestimate  C 's expressiveness.

Actually, that's another thing that I consider to be a serious defect in
C.

"99% of the defects attributed to C are actually defects in C
 programmers. Don't blame the language for the programmer's
 incompetence."

There is a pattern here (i hope you can see it) - things that have
no protection invite errors. Is a saw any less useful if it has
a guard on it?


"Here's a defect: In a program, there are two things: addresses and
 data. Ada takes away 50% of the ballgame--freestyle address
 manipulation--and then calls this a *feature*. This isn't a feature;
 it's Janet Reno Compiler Technology."


Clearly you don't know what you are talking about. Ada has well defined
features for "freestyle" address manipulation. I presume you have not
read the LRM. The difference is that you have to deliberately ask for
it, and can't accidentally stumble on it. Sounds like the power saw
analogy is rather apt, hey?

Programs = addresses + data.  That's pretty lame at best.

1. In Ada you can fiddle "address" stuff if you want (see 'Access and
'Unchecked_Access).

2. If you really are concerned about this sort of expressive
flexibility and freedom, why bother with something as clumsy,
inflexible, and inexpressive as C?  Just go down load CMUCL or get ACL
3.02 and _learn_ what this is really all about.

    O.K. Now I'm confused. Do you mean that the compiler brazenly
    ignores the language standard in the face of flagrant violations
    because it wants to kiss the butt of the programmer who pays it?
    Or do you mean that the compiler looks for flakey programs and
    flames them to the ground in order to prove how macho it is? ;-)
