template <class ForwardIterator> ForwardIterator min_element(ForwardIterator first, ForwardIterator last); template <class ForwardIterator, class BinaryPredicate> ForwardIterator min_element(ForwardIterator first, ForwardIterator last, BinaryPredicate comp);
The two versions of min_element differ in how they define whether one element is less than another. The first version compares objects using operator<, and the second compares objects using a function object comp.
The first version of min_element returns the first iterator i in [first, last) such that, for every iterator j in [first, last), *j < *i is false. The second version returns the first iterator i in [first, last) such that, for every iterator j in [first, last), comp(*j, *i) is false.
int main() { list<int> L; generate_n(front_inserter(L), 1000, rand); list<int>::const_iterator it = min_element(L.begin(), L.end()); cout << "The smallest element is " << *it << endl; }
