Array elements

[Kumar]

How should I declare the array elements being half word?
and the array elements of the type byte in C??

Please help

There's no such C type: you can't portably do it.

If by "half word" you mean some implementation-specific notion,
you'll have to see what your implementation says. It may be,
for example, that your implementation maps C shorts to what
you're calling a "half word" (but another one does not).

If you can use the C99 specified-int types you might be able
to pick one of those that corresponds to your "half word".

Or ... it may be that you don't need to worry about any of
this nonsense. /Why/ do you want to use "half words"?

In C, the nearest you'll get is a (n unsigned) char. This
may or may not correspond to what you want. Why do you want
to use "type byte"?

I think it's *exactly* what he wants. I consider "char" to be synomonous
with "byte".

(But I don't consider a byte to always be 8 bits.)

Until I know what the OP wants "arrays of byte" for, I can't tell if
it's "exactly" what they want.

They might want them for Cunning Type Overlays.

I consider those two as synonomous in a string context,
but in a raw memory context,
unsigned char is what to use to manipulate bytes.

Define what "half word" is.

unsigned char array[N] declares an array of N elements of type unsigned
char, which is the unsigned form of byte, as defined by the C standard.

Maybe your definition of byte is different. If so, provide more
specifics.

Maybe. It's certainly true that a char occupies exactly one "byte" by
definition in C, but that's a C-specific definition of the term
"byte". Given that the OP is asking about this in the first place, I
doubt that he's familiar with the C definition.

I don't think there's any further point in speculating about what the
OP really wants. He can come back and clarify what he means.
