In a recent chat room discussion, pointer notation of arrays in C was
brought up. The question is, are array names pointers? Is array
subscripting another form of pointer notation, or visa-versa? I realize
the pointer notation works for everything except sizeof() (and maybe
others). So that
array == &array[0]
array == &array
*array == array[0]
*(array+n) == array[n]
are all true given array[n]. In this case, sizeof(array) returns the size
of the entire array, not array[0]. Are there other examples where this
pointer notation fails?
Lastly, is this pointer notation implementation dependent or is it part of
the de facto standard?
