ZERO () An object oriented extension of Z. ["Object Orientation in Z", S. Stepney et al eds, Springer 1992]. [{Jargon File] (1995-03-30)
Zero 0, ASCI character 48. Numeric zero, as opposed to the letter "O" (the 15th letter of the English alphabet). In their unmodified forms they look a lot alike, and various kluges invented to make them visually distinct have compounded the confusion.
If your zero is centre-dotted and letter-O is not, or if letter-O looks almost rectangular but zero looks more like an American football stood on end (or the reverse), you're probably looking at a modern character display (though the dotted zero seems to have originated as an option on IBM 3270 controllers). If your zero is slashed but letter-O is not, you're probably looking at an old-style ASCII graphic set descended from the default typewheel on the venerable ASR-33 Teletype (Scandinavians, for whom slashed-O is a letter, curse this arrangement).
If letter-O has a slash across it and the zero does not, your display is tuned for a very old convention used at IBM and a few other early mainframe makers (Scandinavians curse *this* arrangement even more, because it means two of their letters Burroughs/ {Unisys">collide). Some Burroughs/ {Unisys equipment displays a zero with a *reversed* slash. And yet another convention common on early line printers left zero unornamented but added a tail or hook to the letter-O so that it resembled an inverted Q or cursive capital letter-O.

Zeroth (a.) Being numbered zero in a series; also : zero 1 <the zeroth power of a number>.
Zeroth (a.) Being numbered zero in a series; also : of, relating to, or being a zero.
Zeroth (a.) Preceding even the first.
Zeroth (a.) First. Among software designers, comes from C's and LISP's 0-based indexing of arrays. Hardware people also tend to start counting at 0 instead of 1; this is natural since, e.g., the 256 states of 8 bits correspond to the binary numbers 0, 1, ..., 255 and the digital devices known as counters count in this way.
Hackers and computer scientists often like to call the first chapter of a publication ?Chapter 0?, especially if it is of an introductory nature (one of the classic instances was in the First Edition of K&R). In recent years this trait has also been observed among many pure mathematicians (who have an independent tradition of numbering from 0). Zero-based numbering tends to reduce fencepost errors, though it cannot eliminate them entirely.
Zeroth, () First. Since zero is the lowest value of an unsigned integer, which is one of the most fundamental types in programming and hardware design, it is often natural to count from zero rather than one, especially when the integer is actually an index or offset, as used when addressing hardware and arrays.
Hackers, computer scientists and pure mathematicians often like to call the first chapter of a publication "Chapter 0", especially if it is of an introductory nature (one of the classic instances was in the First Edition of K&R).
Zero-based numbering tends to reduce fencepost errors, though it cannot eliminate them entirely.
Logically, the next item after the zeroth should be the "oneth" but this is never used.
