The metric for measuring coupling between two units, is given by :
c (x, y) = i + [n/(n + 1)]
where, the coupling between two units means :
Answer: C
The units are software units.
The formula is the coupling metric proposed by Fenton and Melton for a pair of modules x and y. i is the worst (highest) type of coupling relationship found between the two, on an ordinal scale running from no coupling up to content coupling, and n is the number of interconnections between them. The units being measured are therefore software modules in general, whatever language or paradigm they come from.
The metric is not restricted to classes, objects or methods; those are particular kinds of unit in object-oriented design, and the measure applies to any pair of software units.
