今日课堂练习：vector构造函数

#include 
#include 
using namespace std;
 
void printVector(vector<int> &v)
{
    vector<int>::iterator iter;
 
    for(iter=v.begin(); iter != v.end(); iter++)
    {
    cout << *iter << " ";
    }
    cout << endl;
}
 
int main()
{
    vector<int> v;
    v.push_back(10);
    v.push_back(20);
    v.push_back(30);
    v.push_back(40);
    v.push_back(50);
 
    printVector(v);
 
    vector<int> v2 = v;
    printVector(v2);
 
    vector<int> v3(v2.begin()+2, v2.end());
    printVector(v3);
 
    return 0;
}
