Four program modules form part of a program for a library. A description of the relationship between the modules is summarised as follows: Module name | Description --- | --- UpdateLoan() | • Calls either LoanExtend() or LoanReturn() LoanExtend() | • Called with parameters LoanID and BookID | • Calls CheckReserve() to see whether the book has been reserved for another library user | • Returns TRUE if the loan has been extended, otherwise returns FALSE CheckReserve() | • Called with BookID | • Returns TRUE if the book has been reserved, otherwise returns FALSE LoanReturn() | • Called with parameters LoanID and BookID | • Returns a REAL (which is the value of the fine to be paid in the case of an overdue loan)

1. (a)Draw a structure chart to show the relationship between the four modules and the parameters passed between them.[5]
2. (b)The definition for module LoanReturn() is amended as follows: Module name | Description --- | --- LoanReturn() | Called with parameters LoanID, BookID and Fine | The module code checks whether the book has been returned on time | and then assigns a new value to Fine • LoanID and BookID are of type STRING • Fine is of type REAL Write the pseudocode header for the amended module LoanReturn().[2]
3. (c)A program will: • input 50 unique integer values • output the largest value • output the average of the values excluding the largest value. Draw a program flowchart to represent the algorithm. Variable declarations are not required. It is not necessary to check that each input value is unique.[6]
