Because you can't have negative numbers of elements in an array.

Hi all,
I'm about to start writing an app (Target is iPad running 4.3 or later) but

This question is related to C language, rather than Obj-C.
I have a data structure
typedef struct
{
int x;
int y;
} A;
In my code, I have a function foo(bool xOrY) that runs a long-lasting
loop that iterates through a huge array of A structures and for each
structure, it should get x or y
One Issue I'm having that I forgot to mention is that when I zoom in, the
gesture recogniser on the objects ceases to recognise my attempts to drag and
the scrollview drags instead - I have to zoom back out to near to 1:1 before I
cant start dragging the objects again.
On 30/05/2011, at 21:55 ,
oops, small correction, in the second code sample it should read:
if (xOrY)
{
offset = (char*)&(test.y) - (char*)&test;
}
else
{
offset = (char*)&(test.x) - (char*)&test;
}

Why do you have spaces in your args? It's not going to concatenate them into a
single command line string, it's going to pass them in as the separate args to
the app's "main".

My view isn't even zoomable, but if the text in the textview doesn't completely
fit in the box, when I go to edit it goes from a perfectly legible "long string
with ..." to a very fuzzy "long string with truncation". I'm half-tempted to
just make it non-editable.

Maybe this will assuage your outrage (excuse the lame programmer poetry):
If you were to look at the apis for NSArray and see that indices are signed
integers, you could reasonably conclude that storing/retrieving an object from
a negative index is a legitimate thing to do. That would maybe be
