Customers collect points every time they make a purchase at a store. A program is used to manage the points system and the table lists some of the information stored for one customer. Information Data type required Name String Number of points collected Integer Date of birth Date

1. (a)(i)Identify a suitable structure for storing the information for one customer. Explain the advantage of using this structure. Structure Advantage[4]
2. (a)(ii)Describe a data structure that could be used to store the information for all customers.[2]
3. (b)Customers receive points depending on the amount they spend. The number of points depends on the band that the amount falls into: Band Amount Points 1 Less than 10 5 per whole dollar () 2 Between $10 and $100 inclusive 7 per whole dollar ($) 3 Over $100 10 per whole dollar ($) For example, if the amount is $99.77, this amount is in band 2 and therefore the number of points is 7 x 99, which is 693 points. The algorithm to calculate the points from a given amount is expressed as follows: • work out the appropriate band • calculate and output the number of points. Apply the process of stepwise refinement to increase the detail of the algorithm. Structure your algorithm into a sequence of five steps that could be used to produce pseudocode. Write the five steps. 1 2 3 4 5[5]
