- construction paper — Construction paper is a type of stiff, colored paper that children use for drawing and for making things.
- constructive proof — (mathematics) A proof that something exists that provides an example or a method for actually constructing it. For example, for any pair of finite real numbers n < 0 and p > 0, there exists a real number 0 < k < 1 such that f(k) = (1-k)*n + k*p = 0. A constructive proof would proceed by rearranging the above to derive an equation for k: k = 1/(1-n/p) From this and the constraints on n and p, we can show that 0 < k < 1. A few mathematicians actually reject *all* non-constructive arguments as invalid; this means, for instance, that the law of the excluded middle (either P or not-P must hold, whatever P is) has to go; this makes proof by contradiction invalid. See intuitionistic logic. Constructive proofs are popular in theoretical computer science, both because computer scientists are less given to abstraction than mathematicians and because intuitionistic logic turns out to be an appropriate theoretical treatment of the foundations of computer science.
- continuous process — A continuous process is a process in which the product comes out without interruption and not in groups.
- cornucopian thesis — the belief that, as long as science and technology continue to advance, growth can continue for ever because these new advances create new resources
- counter-hypothesis — a proposition, or set of propositions, set forth as an explanation for the occurrence of some specified group of phenomena, either asserted merely as a provisional conjecture to guide investigation (working hypothesis) or accepted as highly probable in the light of established facts.

- cursor dipped in x — (jargon) The metaphorical source of the electronic equivalent of a poisoned-pen letter. Derived from English metaphors of the form "pen dipped in X" (where X = e.g. "acid", "bile", "vitriol").

He must've had his cursor dipped in acid when he wrote that one!"

- gnu superoptimiser — (GSO) A function sequence generator that uses an exhaustive generate-and-test approach to find the shortest instruction sequence for a given function. Written by Torbjorn Granlund <[email protected]> and Tom Wood. You have to tell the superoptimiser which function and which CPU you want to get code for. This is useful for compiler writers. FTP superopt-2.2.tar.Z from a GNU archive site. Generates code for DEC Alpha, SPARC, Intel 80386, 88000, RS/6000, 68000, 29000 and Pyramid (SP, AP and XP).
