is_sorted

Returns true if the elements in the specified range are in sorted order.

template<class ForwardIterator>
 bool is_sorted(
 ForwardIterator _First, 
 ForwardIterator _Last
 );
template<class ForwardIterator, class BinaryPredicate>
 bool is_sorted(
 ForwardIterator _First, 
 ForwardIterator _Last, 
 BinaryPredicate _Comp
 );

Parameters

• _First
  A forward iterator that indicates where the range to check begins.

• _Last
  A forward iterator that indicates the end of a range.

• _Comp
  The condition to test to determine an order between two elements. A predicate takes a single argument and returns true or false. This performs the same task as operator<.

Property Value/Return Value

Returns true if the elements within the specified range are in sorted order, false if they're not.

Remarks

The first template function returns is_sorted_until(_First, _Last) == _Last. The operator< function performs the order comparison.

The second template function returns is_sorted_until(_First, _Last, _Comp) == _Last. The _Comp predicate function performs the order comparison.
