min_element(b , e)

min_element(b , e, op)

max_element(b , e)

max_element(b , e, op)

op 是函数，函数对象，一元谓词

#include<iostream>#include<algorithm>//#include<deque>bool absLess(int elem1, int elem2){return abs(elem1) < abs(elem2);}using namespace std;int main(){deque<int> ideq;ideq.insert(ideq.end(), -12);for (int i = 2; i <= 8; i++){ideq.insert(ideq.end(), i);}for (int i = -3; i <= 5; i++){ideq.insert(ideq.end(), i);}for (deque<int>::iterator iter = ideq.begin(); iter != ideq.end(); iter++){cout << *iter << ' ';}cout << endl;deque<int>::iterator result = min_element(ideq.begin(), ideq.end());cout << "最小值：" << *result << endl;cout << "最大值：" << *max_element(ideq.begin(), ideq.end()) << endl;cout << "绝对值最小值：" << *min_element(ideq.begin(), ideq.end(), absLess) << endl;cout << "绝对值最大值：" << *max_element(ideq.begin(), ideq.end(), absLess) << endl;//system("pause");return 0;}
