[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.
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.
