NEW Unit III STRUCTURING OF PROGRAM MULTIPLE CHOICE QUESTIONS 1. Which of the following is the functionality of ‘Data Abstraction’? (a) Reduce Complexity (b) Binds together code and data (c) Parallelism (d) None of the mentioned Answer : a Explanation : An essential element of Object Oriented Programming is ‘Data Abstraction’ which means hiding things. Complexity is managed through abstraction. 2. Which of the following mechanisms is/are provided by Object Oriented Language to implement Object Oriented Model? (a) Encapsulation (b) Inheritance (c) Polymorphism (d) All of the mentioned Answer : d Explanation : None. 3. Which of these is the functionality of ‘Encapsulation’? (a) Binds together code and data (b) Using single interface for general class of actions. (c) Reduce Complexity (d) All of the mentioned Answer : a Explanation : ‘Encapsulation’ acts as protective wrapper that prevents code and data from being accessed by other code defined outside the...
