Books were bks and Robin Hood was Rbinhd. Little Goody Two Shoes lost her Os and so did Goldilocks, and the former became a whisper, and the latter sounded like a key jiggled in a lck. It was impossible to read "cockadoodledoo" aloud, and parents gave up reading to their children, and some gave up reading altogether.... - James Thurber, The Wonderful O, 1957 In James Thurber's children's story The Wonderful O, the island of Ooroo is invaded by pirates who set out to banish the letter from the alphabet. Such censorship would be much easier with modern technology. Write a program that asks the user for an input file, an output file, and a string of letters to be eliminated. The program should then copy the input file to the output file, deleting any of the letters that appear in the string of censored letters, no matter whether they appear in uppercase or lowercase form. As an example, suppose that you have a file containing the first few lines of Thurber's novel, as follows: TheWonderfulo.txt Somewhere a ponderous tower clock slowly dropped a dozen strokes into the gloom. Storm clouds rode low along the horizon, and no moon shown. Only a melancholy chorus of frogs broke the soundlessness. If you run your program with the input BanishLetters Input file: TheWonderfulo.txt Output file: TheWnderful.txt Letters to banish: o it should write the following file: TheWnderful.txt Smewhere a pnderus twer clck slwly drpped a dzen strkes int the glm.

If you try to get greedy and banish all the vowels by entering aeiou in response to the prompt, he contents of the output file would be Smwhr pndrs twr clck slwly drppd dzn strks nt th glm.
