求容器中元素的最大最小值

#include<vector>
#include<list>
#include<algorithm>
#include<iostream>
using namespace std;

template<typename T>
void print_max(const T& coll)
{
    typename T::const_iterator iter;
    iter = std::max_element(coll.begin(),coll.end());//主要是这一行,最小用min_element()

    if(iter!=coll.end()){
        cout << *iter << endl;
    }else{
        cout << "empty" << endl;
    }
}

int main()
{
    vector<int> v;
    list<int> l;
    for(int i=0;i<10;++i){
        v.push_back(i);
        l.push_back(i);
    }
    print_max(v);
    print_max(l);
}
