- concrete data structure — (theory) (CDS) A model of programming language terms developed in the context of constructing fully abstract semantics for sequential languages. A CDS is a 4-tuple (C,V,E,|-) where C is a cell, V is a value, E is an event and |- is an "enabling relation". An event is a cell and a value. A cell C is "enabled" by a set of events S if S |- C. A state is a set of events which are consistent in that the values they give for any cell are all equal. Every cell in a state is enabled.
- conditional convergence — the property of an infinite series that converges while the series formed by replacing each term in the given series with its absolute value diverges; the property of an infinite series that converges when the order of the terms is altered. Compare absolute convergence (def 1).
- conjunctive normal form — (logic) (CNF) A logical formula consisting of a conjunction of disjunctions of terms where no disjunction contains a conjunction. Such a formula might also be described as a product of sums. E.g. the CNF of (A and B) or C is (A or C) and (B or C). Contrast Disjunctive Normal Form.
- conservative evaluation — (programming) Under this parallel evaluation strategy, no evaluation is started unless it is known to be needed. The opposite of conservative evaluation is speculative evaluation.

- constant of integration — a constant that is added to the function obtained by evaluating the indefinite integral of a given function, indicating that all indefinite integrals of the given function differ by, at most, a constant.
- conversion to iteration — A transformation applied to functional programs to replace recursion with iteration. A tail-recursive function can be compiled to an iterative loop where the recursive call becomes a jump back to the start and the parameters are held in registers which are updated with new values each time around the loop. See Iteration, Tail recursion optimisation.

- corporate restructuring — a change in the business strategy of an organization resulting in diversification, closing parts of the business, etc, to increase its long-term profitability
- correlation coefficient — a statistic measuring the degree of correlation between two variables as by dividing their covariance by the square root of the product of their variances. The closer the correlation coefficient is to 1 or –1 the greater the correlation; if it is random, the coefficient is zero
