STL list remove和sort函数

#include <iostream>
#include <list>
#include <iterator>

using namespace std;

bool cmp(int a, int b)
{
    return a > b;
}

bool bigger_than_five(int n)
{
    return n > 5;
}

int main()

	list<int> l;
	l.push_back(8);
	l.push_back(7);
	l.push_back(5);
	l.push_back(6);
	l.push_back(8);

	l.sort(cmp); // > 从大到小
	//l.sort(greater<int>());   // > 从大到小

	copy(l.begin(),l.end(),ostream_iterator<int>(cout," "));  //排序后：88765
	cout << endl;

	l.remove(8);

	copy(l.begin(),l.end(),ostream_iterator<int>(cout," "));  //删除8之后: 765
	cout << endl;

	copy(l.begin(),l.end(),ostream_iterator<int>(cout," "));  //删除比5大的数之后:5
	cout << endl;
