[section:find find]
[heading Prototype]
``
template<class SinglePassRange, class Value>
typename range_iterator<SinglePassRange>::type
find(SinglePassRange& rng, Value val);
template<
range_return_value re,
class SinglePassRange,
class Value
>
typename range_return<SinglePassRange, re>::type
find(SinglePassRange& rng, Value val);
``
[heading Description]
The versions of `find` that return an iterator, returns the first iterator in the range `rng` such that `*i == value`. `end(rng)` is returned if no such iterator exists.
2010-04-03 21:00:56 +00:00
The versions of find that return a `range_return`, defines `found` in the same manner as the returned iterator described above.

[heading Definition]
Defined in the header file `boost/range/algorithm/find.hpp`
[heading Requirements]
* `SinglePassRange` is a model of the __single_pass_range__ Concept.
* `Value` is a model of the `EqualityComparableConcept`.
* The `operator==` is defined for type `Value` to be compared with the `SinglePassRange`'s value type.
[heading Complexity]
Linear. At most `distance(rng)` comparisons for equality.
