The index of the first element is 0, unless it is set to 1 by a directive. 5. But there are also collections, modern object-oriented versions of arrays. And the first element of these is usually 1, unless it happens to be 0. Sometimes it is 0 and sometimes it is 1, depending on where you found it. Do you feel lucky, punk? Well, do ya? -- I don't know what they have to say It makes no difference anyway; Whatever it is, I'm against it! [Prof. Wagstaff]

You can also write an off-by-1 bug in loops depending on whether you start the loop with 0 or 1. /BAH

Was that some sort of triumph of the Protestants over the locals? It might have been the only Scotch-Irish congregation in the city, since one fellow came all the way from Staten Island every Sunday.

I've never done a formal count but I suspect that half the patches Microsoft has issued for Windows fix off-by-1 bugs. |
