C++中容器之一deque(双端队列)的问题<2>

#include <iostream>
#include <deque>

using namespace std;

int main()
{
 string str[3]={"程明","程依","钟霞"};
 deque<string> St(str,str+3);
 cout<<St.front()<<endl;
 cout<<St.back()<<endl;

 return 0;
}
在VS2005上和VC6.0上都通不过，问一下，这个该如何解决

#include <iostream>
#include <deque>
#include <string>
using namespace std;

int main()
{
 string str[3]={"程明","程依","钟霞"};
 deque<string> St;
St.push_back(str[0]);
St.push_back(str[1]);
St.push_back(str[2]);
 cout<<St.front()<<endl;
 cout<<St.back()<<endl;
 return 0;
}
