(Mark 5) ////////////////////////////////////////////////////////////////////////////////////////////// My today paper is very simple 5 MCQS from past and 15 mcqs are conceptual Q: Name to two type of structure (2 marks) Q: Define UML methodology its Helpful True or False if true give the reason? (2 marks) Q: How Encapsulation helpful in software engineering? (3 marks) Answer: Encapsulation hides the details of the implementation of an object. Intelligent encapsulation focus design decisions that are likely to change. The ability to change the representation of an object without disturbing any of its clients is the essential benefit of encapsulation. Q: In OO system it’s is possible to increase cohesion and decrease coupling (5 marks) /////////////////////////////////////////////////////////////////////////////////////////// Some of the key advantages which make the object-oriented technology significantly attractive than other technologies include: Clarity and understandability of the system, as object-oriented approach is closer to the working of human cognition. Reusability of code resulting from low inter-dependence among objects, and provision of generalization and specialization through inheritance. Reduced effort in maintenance and enhancement, resulting from inheritance, encapsulation, low coupling, and high cohesion. ///////////////////////////////////////////////////////////////////////////////////////////// Question No: 1 ( Marks: 2 ) Define abstraction ?
