I am unable to compile Ex10_06, the compiler does not recognize the use of greater<double> at the end of the program beginning with:

values.sort(greater<double>());

I copied the code directly out of the book so I didn't mistype and I tried a smaller program using the functional header that has greater and that works. Is anybody else having this problem?

Update: Okay, mystery solved. The sample code I downloaded did not have the statement

using std::greater;

in the beginning. Could also have simply put "using namespace std;"
