equating an array to itself

[Barefootsanders]

Hey all,

I'm trying to use a 3 element array and keep it sorted. So when i get a new value that should be put at the start of the array, I shift values down in the array like this:

array[2] = array[1];
array[3] = array[2];
array[1] = result;

However, I've realized this does not work because of the way arrays are addressed. Is there anyway to do this via unary operators?

Thanks,
barefoot

Nothing to do with it.
Your error is in the subscripts.

array[2] = array[1];
array[1] = array[0];
array[0] = result;

oo wow thanks a bunch. I've been working w/ matlab for to long and it starts with 1 rather than 0 when addressing an array.

Thanks again!

Has nothing to do with whether you start with 0 or 1 in array addressing.
In Pascal you could start from 100 if you wanted to do that.

Look at your code:

array[2] = array[1];
array[3] = array[2];
array[1] = result;

Now look at this code:

array[3] = array[2];
array[2] = array[1];
array[1] = result;

Notice the difference?

Error in coping and pasting.
First line and second line are just swapped.

That is just what Barefootsanders did in the first place ;o)
