template< class T, class CharT, class Traits, class Dist > bool operator==( const istream_iterator<T,CharT,Traits,Dist>& lhs,                  const istream_iterator<T,CharT,Traits,Dist>& rhs );	(1)
template< class CharT, class Traits > bool operator!=( const istream_iterator<T,CharT,Traits,Dist>& lhs,                  const istream_iterator<T,CharT,Traits,Dist>& rhs );	(2)

Checks whether both lhs and rhs are equal. Two stream iterators are equal if both of them are end-of-stream iterators or both of them refer to the same stream.

1) Checks whether lhs is equal to rhs.

2) Checks whether lhs is not equal to rhs.

Parameters

lhs, rhs

-

stream iterators to compare

Return value

1) true if lhs is equal to rhs, false otherwise.

2) true if lhs is not equal to rhs, false otherwise.

Exceptions

(none)
