vector和deque容器提供了对元素的快速随机访问，但是，在容器的任意位置插入或删除元素，比在容器尾部插入和删除的开销更大，list类型在任何位置都能快速插入和删除，但是随机访问开销更大

示例是最好的理解方法

    cout << "ivec.size: " << ivec.size() << endl;  
  
    vector<int> ivec2(ivec);
    if (ivec2.empty() == false) {
        for (vector<int>::size_type ix = 0; ix != ivec2.size(); ++ix)
			 cout << ivec2[ix] << endl;
     }

vector和deque容器提供了对元素的快速随机访问，但是，在容器的任意位置插入或删除元素，比在容器尾部插入和删除的开销更大，list类型在任何位置都能快速插入和删除，但是随机访问开销更大
