NAME greater_equal - A 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> { 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 is sorted in descending order. WARNINGS If your compiler does not support default template parame- ters, then you always need to supply the Allocator template argument. For instance, you have to write: vector<int, allocator<int> > instead of vector<int> If your compiler does not support namespaces, then you do not need the using declaration for std.
