Question 3 (25 marks) This question focuses on Part 3 (selection) and Part 4 (repetition). As inspiration for this question, you might like to revisit Activity 4.8 of Part 4, which

uses a list of specific characters. The teacher wishes to see if her pupils can make sense of words in which certain letters have been removed. She requires a when[space]key_pressed script that will take a word from the user and display a new word that is the same as the original except that each vowel has been removed. For clarification, the vowels should be considered as: a, e, i, o and u. The user should input the word as a single string and the new word that is displayed should be a single string. For example, if the user enters 'raise' then 'rs' is displayed. One way to create the new word to be displayed is to start with the new word as an empty string and then work through the letters in the original word from first to last, creating the new word incrementally. If the current letter is not a vowel then we add it to the new word, otherwise we ignore it. This might be visualised as in Figure 2. Figure 2 Recall that, as in Part 4 Activity 4.8, a simple way to check whether a given character is one of a set of specific characters is to check whether it is in a list that has been populated with those specific characters. a. b. C. Create and write down an algorithm to solve this problem. You might like to use the idea above, or an alternative of your own. 1 (10 marks) Create a when[space]key_pressed script to implement your algorithm. Depending on your algorithm and the way in which you choose to implement it, you may also decide to have a when_green_flag_clicked script. Take a screenshot of your script(s) and paste it into your TMA document. (11 marks) Copy the following table into your TMA document and add to it two tests you would perform to check whether the completed program fulfils the specification. (Several tests might be appropriate; however, you are only required to add two.) Test number Test purpose Inputs Expected results New word displayed ppl Word First and last letters are vowels apple 7 of 11/n2 3 (4 marks) Save your OUBuild project for Question 3 and submit it as TM111_02_Q3_PI. sb2 (where Pl is your OU personal identifier, e.g. A1234567) in your TMA zip file. Alternatively, you may use your OUCU instead of your Pl.
