为什么无法继续读取输入？
代码如下：
#include <iostream>
#include <vector>
using namespace std;
int main()
{
vector <int> vec1,vec2;
int tem;
cin> > tem;
while(tem)
{
vec1.push_back(tem);
cin> > tem;
}
cout < < "Vector1 initialized! " < <endl;
cin.clear();//将流恢复为有效状态
cin> > tem;
while(tem)
{
vec2.push_back(tem);
cin> > tem;
}
cout < < "Vector2 initialized! " < <endl;
size_t n=vec1.size() <vec2.size()?vec1.size():vec2.size();
for(vector <int> ::iterator iter1=vec1.begin(),iter2=vec2.begin();iter1!=vec1.begin()+n;++iter1,++iter2)
{
if((*iter1)!=(*iter2))
{
cout < < "No!!! " < <endl;
break;
}
}
if(vec1.size()==vec2.size())
cout < < "Equal! " < <endl;
else if(vec1.size()> vec2.size())
cout < < "Vector2 is the profix of Vector1 " < <endl;
else
cout < < "Vector1 is the profix of Vector2 " < <endl;
system( "Pause ");
return 0;
}
问题为初始化第一个Vector之后程序就死了，不知道为什么啊？？？那位高手帮我解答一下！！！！

试了一下你的程序: 当输入正确时(输入为int)没问题.
当输入无效时(输入字母),如你所说,程序就死了.
因此,你要加上输入有效性判断.
[解决办法]
#include <iostream>
#include <vector>
using namespace std;
int main()
{
vector <int> vec1,vec2;
int tem;
while(cin> > tem) // !!!
{
vec1.push_back(tem);
}
cout < < "Vector1 initialized! " < <endl;
cin.clear();//将流恢复为有效状态
while (cin.get() != '\n ') // !!!
{
continue;
}
while(cin> > tem) // !!!
{
vec2.push_back(tem);
}
cout < < "Vector2 initialized! " < <endl;
size_t n=vec1.size() <vec2.size()?vec1.size():vec2.size();
for(vector <int> ::iterator iter1=vec1.begin(),iter2=vec2.begin();iter1!=vec1.begin()+n;++iter1,++iter2)
{
if((*iter1)!=(*iter2))
{
cout < < "No!!! " < <endl;
break;
}
}
if(vec1.size()==vec2.size())
cout < < "Equal! " < <endl;
else if(vec1.size()> vec2.size())
cout < < "Vector2 is the profix of Vector1 " < <endl;
else
cout < < "Vector1 is the profix of Vector2 " < <endl;
system( "Pause ");
return 0;
}

你的VECTOR应该有点问题：你输入的0是VECTOR中的
可是你去拿它当VECTOR的结束的判断！
我觉得应该动态的申请去初始化VECTOR！（个人意见）！
