For lab 2, you will be implementing problems from the textbook.

Please implement coding exercise 1-5 from the end of Chapter 2 in the
textbook.  For 2, 3, and 5, ignore the bit about allowing the user to
perform the calculation as often as they wish.  Once through the
program will be acceptable.

Make sure you use meaningful variable names, as well as adequate
output to indicate to the user what input is required.

Comments, style, and presentation quality count.

Please email all files to the instructor, after creating a bzip'd
tarball (instructions are at the end of the first lab).
