Changes can only be made within the framework of encapsulation. Undisciplined changing of data values was considered one of the weaknesses of structured programming. This is corrected in object-oriented programming. Figure 1. Instance variables and methods. Here is a/

Richard C. Lee and William M. Tepfenhart 2 Introduction The key to object-oriented programming is to model the application in terms of cooperative objects that reflect reality. You design classes that describe the behavior of these objects. Carefully designed classes are the key to a successful application.
