代码如下:

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;void myPrint(int val)
{cout << val << " ";
}void test01()
{vector<int>v;v.push_back(10);v.push_back(30);v.push_back(50);v.push_back(20);v.push_back(40);v.push_back(60);sort(v.begin(), v.end());for_each(v.begin(), v.end(), myPrint);cout << endl;sort(v.begin(), v.end(), greater<int>());for_each(v.begin(), v.end(), myPrint);cout << endl;
}int main()
{test01();return 0;
}
