title: 2 bits can store 4 different values?
body: <p>In 
  <a href="http://www.learncpp.com/cpp-tutorial/23-variable-sizes-and-the-sizeof-operator/" rel="nofollow">learncpp</a> I noticed that it says that 2 bits can store 4 different values and they give an example in the table.  I am somewhat confused by what they mean.  My original interpretation was that 2 bits can only store 2 values (ie. just 0 and 1 since the definition of a binary digit is 0 or 1).  However after looking at the table, do they mean that two bits can store 4 different COMBINATIONS of values (ie. 00 01 10 11).  </p>
