A novel coupling metrics measure difference between inheritance and interface to find better OOP paradigm using C#

A large numbers of metrics have been proposed for measuring properties of object-oriented software such as size, inheritance, cohesion and coupling. The coupling metrics presented in this paper exploring the difference between inheritance and interface programming. This paper presents a measurement to measure coupling between object (CBO), number of associations between classes (NASSocC), number of dependencies in metric (NDepIN), number of dependencies out metric (NDepOut) and Number of children (NOC) in object oriented programming. A measurement is done for C# inheritance and interface programs. The metric values of class inheritance and interface prove which program is good to use and beneficial for C# developers.
