ABSTRACT:The concepts of structured and object-oriented programming methods are not relatively new but these approaches are still very much useful and relevant in today's programming paradigm. In this paper, we distinguish the features of structured programs from that of object oriented programs. Structured programming is a method of organizing and coding programs that can provide easy understanding and modification, whereas objectoriented programming (OOP) consists of a set of objects, which can vary dynamically, and which can execute by acting and reacting to each other, in much the same way that a real-world process proceeds (the interaction of realworld objects). An object-oriented approach makes programs more intuitive to design, faster to develop, more amenable to modifications, and easier to understand. With the traditional, procedural-oriented/structured programming, a program describes a series of steps to be performed (an algorithm). In the object-oriented view of programming, instead of programs consisting of sets of data loosely coupled to many different procedures, objectoriented programs consist of software modules called objects that encapsulate both data and processing while hiding their inner complexities from programmers and hence from other objects. @ JASEM Structured programming can be viewed as the pulling together, or synthesization of such ideas as program modularity and top down design, and the concrete representation of them at the program-coding level. It is a manner of coding and organizing programs that makes them easier to understand, to test and to modify. Results have demonstrated that employed together with other improved programming technologies, can lead to spectacular increases in programmer productivity and correspondingly spectacular decreases in the error rate of resultant code (Champeaux, 1990), and(Istatkova, 2001). Structured programming methodology tries to resolve the issues associated with unconditional transfers to enable programmers follow the logic of programs.
