Why use pointers at all??

Use of *p++ notation rather than p[i++] helps reduce portability to
other languages, which often is a goal. I doubt many would give up both
styles. Or, do you campaign for C not to be used where one of these
notations would be useful?

Why? Are you afraid they will point at you?

Because it doesn't make sense to use arrays to point to things?
Hint: Do 5 seconds of embedded software work and re-think your
question.

No reason at all, if you don't want to. So don't bother, until a need for
them arises.

Explain to me how you'd use memory mapped I/O then?

So you can do things you can't easily do without them.

My point is this: that the OP will, in due course, discover a need for
pointers. Clearly he or she hasn't yet reached this point. It is not
unusual for newbies to ask this question, and almost invariably anyone who
tries to explain it to them faces a barrage of objections and confusions.
So I thought I'd try a different approach. "Okay, if you don't see a need
for them, great! Do whatever you do, without them." At some point, such an
approach will lead to a brick wall, with a door in it labelled "Pointers"
that swings invitingly ajar.

Hi,
I'm just reading about smart pointers..
I have some existing C code that I would like to provide wrapper classes
for. Specifically, I would like to provide wrappers for two stucts
defined as ff:
typedef struct {
float *data ;
int count ;

This is probably an obvious question.
I know that pointer comparisons are only defined if the two pointers
point somewhere "into" the storage allocated to the same object, or if
they are NULL, or one-past the end of the object as long as it isn't
dereferenced.
I use "object" in the standard 'C' sense.
Is there some special dispensation given to comparing two pointers

Hello!
I'd like to have a variable of a pointer-to-function type. The two possible
values are of type (*)(FILE *) and (*)(void *). For example:
getter = straight ? fgetc : gzgetc;
nextchar = getter(file);
What type should I give to `getter' so that the compiler does not issue

VB.NET (v2003) does not support pointers, right? Assuming that this is true, are there any plans to support pointers in the future? Forgive my ignorance, but if C# supports pointers and C# and VB.NET get compiled into the same code, then I don't understand why VB.NET can't support pointers
Thanks for any info
Lance

Someone made the statement in a newsgroup that most C++ programmers use
smart pointers. His actual phrase was "most of us" but I really don't think
that most C++ programmers use smart pointers, but I just don't know.
I don't like them because I don't trust them. I use new and delete on pure
pointers instead.
Do you use smart pointers?

In C you can compare two pointers, p<q, as long as they come from the
same array or the same malloc()ated block. Otherwise you can't.
What I'd like to do is write a function
int comparable(void *p, void *q)
that will take any two pointers and decide whether they can be compared
or not.
I really can't think how to do this - any suggestions?

use the Boost smart pointers) as I'm seriously concerned that there is a
