This solution is for the book I am currently reading. All of my notes and solutions are available at Google Code.

Here is my work for problem 2.15:

Fill in the table below showing the effects of the different shift operations
on single-byte quantities. The best way to think about shift oeprations
is to work with binary representations. Convert the initial values to binary, 
perform shifts, and then convert back to hexadecimal. Each of the answers 
should be 8 binary digits or 2 hexadecimal digits.
