  One interesting approach to this is to use a type of container called a
'map'.   (Without trying to validate this; beware) Basically,

  // Declare associative array named 'senderCount' of template type map
keyed by string containing int values
  map senderCount;

  string email;

You can manipulate the values like this:
 senderCount[email]=0;
 senderCount[email]++;

   o  The senderCount data is sorted
   o  You don't have to linearly search an array to update the random
string values coming from the log file (much faster).

 [It's left as an exercise how to detect whether to increment an existing
map value or initialize a new value to zero]


  Microsoft heathens can also use CMap, which is documented better in the
MSDN.   If you use STL (recommended), plan on using supplemental reference
materials.
