Chapter 10.  Exceptions


In this chapter you learned about built-in exceptions. Here are some projects that will help you test the depth of your understanding.

1)

Create the following script. For each section determine the number of students registered. If this number is equal to or greater than 15, raise the user-defined exception e_too_many_students and display the error message. Otherwise, display how many students are in a section. Make sure that your program is able to process all sections.

2)

Modify the script you created in the previous exercise. Once the exception e_too_many_students has been raised in the inner block, re-raise it in the outer block.

The projects in this section are meant to have you utilize all of the skills that you have acquired throughout this chapter. The answers to these projects can be found in Appendix D and at the companion Web site to this book, located at http://www.phptr.com/rosenzweig2e. Visit the Web site periodically to share and discuss your answers.
