It is interesting to examine how the ratio (N – N ) IN varies when a program is divided into- parts (Actually, some experiment show that the partitioning of Vocabularies due to program modularization maintains the stability of the Wo extreme situations may occur: a. rh and Th are the same for all parts; b. ni and 772 are partitioned into disjoint subsets by modularization. Compute the variations of N for a program with N = N = 72, ni = 4, and ri2 = 16 when the program is divided into two parts, under the two extreme assumptions. : It may be difficult to “divide” a program in such a way as to satisfy the second assumption. (At least one procedure definition and call must share an identifier.) For large values of the quantities involved, however, we can at least assume that. Th and th ' have small intersections with respect to their size.
