(a) All variables, constants and other identifiers should have meaningful names. (i) For one variable that you have used to record the information about a single boat in Task 1, state the name, data type and its use. Variable name \_\_\_\_ Data type \_\_\_\_ Use \_\_\_\_ (ii) State one constant and its value that you could have used for Task 1. Constant name \_\_\_\_ Value \_\_\_\_ (b) Give two different validation checks you could have used for data entry in Task 1. For each check explain why it could be used and provide a set of data for testing. Validation check 1 \_\_\_\_ \_\_\_\_ Reason for choice \_\_\_\_ \_\_\_\_ Set of test data \_\_\_\_ \_\_\_\_ Validation check 2 \_\_\_\_ \_\_\_\_ Reason for choice \_\_\_\_ \_\_\_\_ Set of test data \_\_\_\_ \_\_\_\_ (c) Write an algorithm to complete Task 3, using either pseudocode, programming statements or a flowchart. You may assume Task 2 has been completed. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ (d) Explain how your program finds out how many boats are available for hire (Task 2). Any programming statements used must be fully explained. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_
