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.
