(a) All variables, arrays, constants and other identifiers should have meaningful names. (i) State the name of one variable you have used for Task 3. Give the data type for the variable. State what it is used for. Variable name \_\_\_\_ Data type \_\_\_\_ Use \_\_\_\_ [3] (ii) Describe the arrays that you have used to store the data for the children in Task 1. Include the name, data type and its use for each array. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [5] (b) Explain how you ensured that each identification number entered in Task 1 was unique and included a correct check digit. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [4] (c) Write an algorithm for Task 2, using either pseudocode, programming statements or a flowchart. You should assume that Task 1 has already been completed. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ (d) Explain how your program identifies and outputs the names and times of the fastest runner for each age range in Task 3. Any programming statements used in your answer must be fully explained. Do not include the wristband check or PB time update. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_
