In-class Lab Assignment

October 5, 2006

This assignment is to be completed during the class period and submitted to the Digital Dropbox as yourname4 at the end of the period WHETHER OR NOT YOU HAVE COMPLETED IT CORRECTLY. If you can not finish it, submit it anyway and then go home and finish it over the weekend and re-submit it with the same name but add a comment saying with the words “final version”. PLEASE do NOT submit MULTIPLE FINAL versions. It MUST be completed by the start of class on Tuesday, Oct 10^th. Bring print-outs of your FINAL version to class on Tuesday with your test input and the output produced by your program. Do NOT include them with your electronic submission and therefore don’t zip your file.

Write a Pascal program which will use an array of Strings where the Strings are defined by your program to be a packed array of characters. The problem you are to solve is that of reading in words from a FILE where there may be multiple words on a line. The words will all be less than or equal to 10 characters in length. The words are separated by a blank (i.e. that is how you can determine where a word ends). You should read until there are no more words left (i.e. you have reached the end of file – Pascal has an EOF function). There will not be more than 25 words. Once you have read in all the words, print them out to the output file in alphabetical order, one per line.

As usual

• You need the standard heading; you should tell the user what the program is going to do
• You should echo each word as you read it
• You do NOT have to echo the words as you read them to the output file
• The user should provide the input and output file names to your program.
• You should use subprograms where appropriate
• Your program should label its output
• Your program should tell the user what the names of the input and output files were
• Your program should print a message saying that the program has ended normally.
• You should NOT read all of the data in as a giant string and parse the string
