All variables, constants and other identifiers should have meaningful names. Here is a copy of the pre-release material. DO NOT attempt Tasks 1, 2 and 3 now. Use the pre-release material and your experience from attempting the tasks before the examination to answer Question 1. Pre-release Material Write and test a program to complete the three tasks. TASK 1 A data logger records the temperature on the roof of a school twice a day, at midday and midnight. Input and store the temperatures recorded for a month. You must store the temperatures in two one-dimensional arrays, one for the midday temperatures and one for the midnight temperatures. All the temperatures must be validated on entry and any invalid temperatures rejected. You must decide your own validation rules. You may assume that there are 30 days in a month. TASK 2 Calculate the average temperature for midday and the average temperature for midnight. Output these averages with a suitable message for each one. TASK 3 Select the day with the highest midday temperature and the day with the lowest midnight temperature. Then output each of these temperatures, the corresponding day and a suitable message. Your program must include appropriate prompts for the entry of data. Error messages and other outputs need to be set out clearly and understandably. All variables, constants and other identifiers must have meaningful names. Each task must be fully tested.

1. (a)(i)In Task 1, you had to store the midday temperatures and midnight temperatures in arrays. Write suitable declarations for these two arrays.[2]
2. (a)(ii)It has been decided to record the temperatures for one week rather than one month. Write the new array declarations that you would use.[1]
3. (a)(iii)Declare two other variables that you have used and state what you used each one for. Variable 1 Use Variable 2 Use[4]
4. (b)Write an algorithm to complete Task 2, using either pseudocode, programming statements or a flowchart. Use temperatures for one week only. You should assume that Task 1 has already been completed.[5]
5. (c)Give a set of midday temperature data, for a week, that could be used to check your validation rules for Task 1. Explain why you chose this data set. Data set Reason for choice[2]
6. (d)Explain how you select the day with the highest midday temperature (part of Task 3). You may include pseudocode or programming statements as part of your explanation.[6]
