"&" is a bit-wise operator.  Here is a description of how it works:
      http://www.codeproject.com/cpp/bitbashing.asp

"&&" is a logical "and" operator.  Basically it works like this:

A && B = X

     If A is true (not 0) AND B is true, then X will be True (1).
     If either A or B is not true (equal to 0), then X will be False.

Hope that helps,
Dex*
