Lab 13: Instructor's Notes

The lab exercise asks the students to run some time experiments There are a few things for you to do and consider:

• Try the experiments yourself to see how well the clock() function measures time on your system.
  • You may want to change the number of iterations that each driver spends running its tests.
  • You may want to change the sample range of n.
• Students need to graph their timing results, and it is suggested that a spreadsheet program be used for this. Make sure the students have one available to them.

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 before, they could also be used as "postlab" exercises.
• The lab home page Note: I have not used this lab exercise in my C++ programming course for engineers. The number of class hours and term length simply prevented it. It is essentially the same as a lab exercise prepared by Jeremy Frens for the text C++: An Introduction to Computing — Third Edition written by Joel Adams and myself.
• Other programming projects from or in addition to those in the textbook that tie in with the material in this lab exercise.
  Also, A gradesheet that might be used with one of these projects.
