• What code qualities are required to maintain to keep code flexible?
• To Understand the common design patterns.
• To explore the appropriate patterns for design problems

Course Outcomes: The student will be able to :

• Design and implement codes with higher performance and lower complexity
• Be aware of code qualities needed to keep code flexible
• Experience core design principles and be able to assess the quality of a design with respect to these principles.
• Capable of applying these principles in the design of object oriented systems.
• Demonstrate an understanding of a range of design patterns. Be capable of comprehending a design presented using this vocabulary.
• Be able to select and apply suitable patterns in specific contexts

Question Paper Pattern:

• The question paper will have ten questions.
• Each full Question consisting of 20 marks
• There will be 2 full questions (with a maximum of four sub questions) from each module.
• Each full question will have sub questions covering all the topics under a module.
• The students will have to answer 5 full questions, selecting one full question from each module.
