Two questions from the 2010 HSC paper.
Anyone got some good answers for these about Library Routines?

c) i) What are the benefits of using library routines? ---> 2 marks
ii) Describe the requirements of library routines that need to be considered during their development. ---> 3 marks

Sample answers:

Question 21 (c)(i)
Answers could include:
• Saves development time
• Routines are already tested hence saves testing time
• Helps maintenance by providing well-understood standard routine with consistent behaviour
• Library routines can be updated independently
• Library routines can be re-used by a variety of different providers without modification

Question 21 (c)(ii)
Answers could include:
• Deciding whether the library routine is appropriate for a range of production uses
• Consider the parameters that need to be passed
• Need for thorough testing under a range of conditions
• Thorough documentation of the purpose and expected inputs and outputs of the routine.
