C++中Vector求最大值最小值

#include <iostream>
#include <vector>
#include <windows.h>
#include <algorithm>

using namespace std;

int main()
{
    vector<int> vec = {-7, 1, 10, 7, 2, 1};

    vector<int>::iterator itMax = max_element(vec.begin(), vec.end());
    vector<int>::iterator itMin = min_element(vec.begin(), vec.end());

    cout << "最大值为：" << *itMax << " " << "所在位置：" << distance(vec.begin(), itMax) << endl;
    cout << "最小值为：" << *itMin << " " << "所在位置：" << distance(vec.begin(), itMin) << endl;

    system("pause");
    return 0;
}

vector<int> v:
最大值：
int max =  *max_element(v.begin(),v.end());  
最小值：
int min = *min_element(v.begin(),v.end());

int a[]={1,2,4,6,4,9};
vector<int>sums(a,a+6);
        int idx = max_element(sums.begin(),sums.end())-sums.begin();
