Lab 6: Instructor's Notes

This is a first "serious" look at classes — the string class, in particular — and probably the first look at them for some (perhaps most) students, even if they've already done some progamming in the past. For this reason, the author has used the Prelab questions as "Test Yourself" questions assigned to be done after the lab exercise and handed in.

The lab studies strings in the context of developing a preliminary version of a Pig-Latin to English translator. One of the homework problems continues this development and you may want to consider assigning it.

Here are:

• Prelab Questions designed to check if students have read through the lab exercise in preparation for doing the lab exercise. However, as noted above, they may, alternatively, be used as "postlab" exercises that test how well the students understood the lab exercise.
• The lab home page
• The first programming project extends the pig-latin translator begun in the lab exercise. Two of the other string-processing programming projects deal with encryption schemes and another is a palindrome checker.
• A gradesheet used by the author for the project assigned.
