find


Category: algorithms 
Component type: function 
Prototype
template<class InputIterator, class EqualityComparable>
InputIterator find(InputIterator first, InputIterator last,
const EqualityComparable& value);
Description
Returns the first iterator i in the range [first, last) such that
*i == value. Returns last if no such iterator exists.
Definition
Defined in the standard header algorithm, and in the nonstandard
backwardcompatibility header algo.h.
Requirements on types

EqualityComparable is a model of EqualityComparable.

InputIterator is a model of InputIterator.

Equality is defined between objects of type EqualityComparable and
objects of InputIterator's value type.
Preconditions

[first, last) is a valid range.
Complexity
Linear: at most last  first comparisons for equality.
Example
list<int> L;
L.push_back(3);
L.push_back(1);
L.push_back(7);
list<int>::iterator result = find(L.begin(), L.end(), 7);
assert(result == L.end()  *result == 7);
