NAME

  greater_equal  - Binary function object that returns true if its first
  argument is greater than or equal to its second

SYNOPSIS

  #include <functional>

  template <class T>
  struct greater_equal ; : binary_function<T, T, bool> {
   typedef typename binary_function<T, T, bool>::second_argument_type
                                                 second_argument_type;
   typedef typename binary_function<T, T, bool>::first_argument_type
                                                 first_argument_type;
   typedef typename binary_function<T, T, bool>::result_type
                                                 result_type;
   bool operator() (const T&, const T&) const;
  };

DESCRIPTION

  greater_equal is a binary function object.  Its operator() returns true if
  x is greater than or equal to y.  You can pass a greater_equal object to
  any algorithm that requires a binary function.  For example, the sort
  algorithm can accept a binary function as an alternate comparison object to
  sort a sequence.  greater_equal would be used in that algorithm in the
  following manner:

  vector<int> vec1;
  sort(vec1.begin(), vec1.end(),greater_equal<int>());

  After this call to sort, vec1 will be sorted in descending order.

WARNINGS

  If your compiler does not support default template parameters, then you
  need to always supply the Allocator template argument.  For instance,
  you'll have to write :

  vector<int, allocator<int> >

  instead of

  vector<int>
