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 parameters, 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.
