AQA A LEVEL Computer Science PAPER 2 (a) Write the function getText (b) The procedure, fullStop, needs to: • ask for a file name as input • read the data from the file using the function getText • replace the first letter after each full stop with a capital letter if it is currently lower case (if the next character is a space, it must check each successive character until it finds a letter) • write the edited data back to the text file. You can assume the text file only contains upper and lower case letters, spaces and full stops. Part of the ASCII table has been provided: ASCII Value Character 65 "A" 90 "Z" 97 "a" 122 "z" 32 " " (space) 46 "."
