CSc 221 Spring 2006 Homework 2

Due before the start of class on Thursday, Feb 23. NOTE that there is no school on Monday Feb 13 (Lincoln's Birthday) or Feb 20 (President's Day). AND Tues Feb 21 follows a Monday schedule. We do not meet.

You are to prepare a program that will produce a screen something like this:

Your program is to do considerable checking:

• Make sure that required fields have something in them
• The middle initial is just one letter, if present at all.
• The city is from one to four words.
• The state is two letters.
• The ZIP is five digits
• The phone number has the right number of digits in each field, and the first number of the area code is not zero or one.
• The Social Security Number has the right number of digits in each field.

Don't try to match this appearance, at all. That is not the point of the assignment. In fact, you are free to try to improve the layout. (But you are not required to do so.)

I may not be able to give you too much guidance on this. Look on the course CD, in the folder named HW1and2Fall2005, where you will find samples of program elements like what you need here. Homework 2 there is done in quite different ways, in some regards. The main thing is the regular expression examples near the end of the program. Regular expressions are discussed in Chapter 29 of the text.

The two main issues in the homework are the layout and the use of regular expressions for the validity checking.
