• Announcements
  • Reminder: all questions about grading of Exam 1 should be asked by Monday
  • Tentative date for Exam 2: November 15
• Lecture assignment 14 recap
• In-class exercise.

  We will do this together as a class. As we go, you should be developing your own version of the flowchart to be submitted for 10 lecture assignment points. You may work alone or partner with a neighbor for this.

  We will develop a flowchart for a program that reads in words, one by one, until we enter the empty string. It keeps track of how many words were read in and the longest word or words, and reports both at the end.

  We will develop the flowchart incrementally, just as you should be doing for the current lab.

  Here are the steps we will follow:

  1. Read in one word.
  2. Read in words inside a loop (forever).
  3. Read in words until someone enters the empty string ("").
  4. Add a variable that keeps track of the number of words read in. Initialize it before your main loop, increment it in an appropriate place inside your main loop, and print it out after the loop.
  5. Add a variable to keep track of the longest word. Update it in your main loop any time someone enters a word longer than the longest seen previously. Print it out at the end. Don't worry yet about handling ties.
  6. Now worry about that case. When you detect a tie for the longest word, you should append the new word to the string containing the longest word(s). Note that we will now need to have a separate variable to remember the length of the longest word, since the string containing the longest word(s) may now contain multiple words.
  7. Add a check at the end to make sure you only print the longest word(s) if at least one word was entered before "" was entered. If not, print a separate message to that effect.

  When finished, save and submit your flowchart under "Lecture 15 In-Class Assignment" on Blackboard. If you worked with a partner, make sure both names are included in the "Comments" in Blackboard so both partners receive credit. Again, this submission will earn you 10 lecture assignment points.

• Continue work on Lab 6: Grade Summary Calculator
  • due Monday at 11:59 PM
  • don't forget the "Comparison of Visual Logic and Java 6 Syntax" document in Blackboard under "Files and Documents" to help you remember the syntactic differences between VL and Java
