#include<iostream>
#include<vector>
#include<list>
using namespace std;

int main()
{
    vector<int> ivec;
    list<int> ilst;
    int ival;
    cout<<"Enter some integers for vector (Ctrl+Z to end):"<<endl;
    while(cin>>ival)
        ivec.push_back(ival);
   
    cin.clear();
    cout<<"Enter some integers for list (Ctrl+Z to end):"<<endl;
    while(cin>>ival)
        ilst.push_back(ival);
     为什么这里ilst获取不到值呢
    vector<int>::iterator vit=ivec.begin();
    list<int>::iterator lit=ilst.begin();
    while(vit!=ivec.end()&&lit!=ilst.end())
    {
        if(*vit!=*lit)
            break;
        ++vit;
        ++lit;
    }
    if(vit==ivec.end()&&lit==ilst.end())
        cout<<"The vector contains the same elements as the list."<<endl;
    else
        cout<<"List and vector contains different elements."<<endl;
    return 0;
}

没有问题的，测试结果如下：
Enter some integers for vector (Ctrl+Z to end):
1
^Z
^Z
Enter some integers for list (Ctrl+Z to end):
2
3
^Z
^Z
List and vector contains different elements.

可以在    ilst.push_back(ival);这一行设置断点，
看看是否真正进来了，好好研究一下如何结束cin的操作，
就应该找到程序的问题啦~~~

祝你好运~~

另外一个测试结果
Enter some integers for vector (Ctrl+Z to end):
1
^Z^Z
^Z
Enter some integers for list (Ctrl+Z to end):
1
^Z
^Z
The vector contains the same elements as the list.

谢谢大虾
