大家帮我看个错误啊，纠结

#include<cstdio>
#include<iostream>
#include<cstring>
#include<vector>
#include<iterator> using namespace std; int main()
{
vector<string> vt;
string s1,s2,s;
int n;
cin>>n;
for(int i=0;i!=n;++i) cin>>s;
vt.push_back(s);
}
for(vector<string>::size_type i=0;i!=vt.size();++i)
{
cout<<vt[i]<<endl;
}
cout<<"我是华丽的分割线======================"<<endl;
for(vector<string>::iterator it=vt.begin();it!=vt.end();++it)
{
cout<<*it<<endl;
}
return 0;
}
