We have arrived in the hot, wet city of Bangkok. This is our first trip to Thailand(泰国). All the different smells make us want to try the food. We are going to eat something special for dinner tonight. The hotel we are staying in is cheap, and very clean. We plan to stay here for a few days, visit some places in the city, and then travel to Chiang Mai in the North.
Tuesday, March 27th
Bangkok is wonderful and surprising. The places are interesting. We visited the famous market which was on water, and saw a lot of fruits and vegetables. Everything is so colorful, and we have taken hundreds of photos already! Later today we will leave for Chiang Mai. We will take the train north, stay in Chiang Mai for two days, and then catch a bus to Chiang Rai.
Friday, March 30th
Our trip to Chiang Rai was long and boring. We visited a small village in the mountains. The village people here love the quiet life—no computers or phones. They are the kindest people I have ever met. They always smile and say“hello”. Kathy and I can only speak a few words of Thai, so smiling is the best way to show our kindness. I feel good here and hope to be able to come back next year.

文明指文化发展中的进步方面。任何时代和地域的民族、部落或人群都有自己的文化,但不一定有文明。
阅读以下说明和C++代码,将应填入______处的字句写在对应栏内。
[说明]
已知类LinkedList表示列表类,该类具有4个方法:addElement()、lastElement()、numberOfElement()以及removeLastElement()。4个方法的含义分别如下。
· void addElement(Obect):在列表尾部添加一个对象。
· Object lastElement():返回列表尾部对象。
· int numberOfElement():返回列表中对象的个数。
· void removeLastElement():删除列表尾部的对象。
现需要借助LinkedList来实现一个Stack栈类,C++代码1和C++代码2分别采用继承和组合的方式来实现。
[C++代码1]
Class Stack:public LinkedList
public:void push(Object o)(addElement(o);; //压栈
Object peek()return ______;; //获取栈顶元素
bool isEmpty() //判断栈是否为空
return numberOfElement()==0;;
Object pop //弹栈
Object o=lastElement();
______;
Return 0;
;
;
[C++代码2]
class stack
private:
______;
public:
void push(Object o) //压栈
list.addElement(o);
;
object peek //获取栈顶元素
return list ______;
;
bool isEmpty() //判断栈是否为空
retum list.numberOfElement()==0
;
Object pop() //弹栈
Objecto=list.lastElement();
list.removeLastElement();
return o;
;
[问题]若类LinkedList新增加了一个公有的方法removeElement(int index),用于删除列表中第index个元素,则在用继承和组合两种实现栈类Stack的方式中,哪种方式下Stack对象可访问方法removeElement(int index)______(A.继承B.组合)
