vc编译问题？？救急！！

[hewittlee]

#include <iostream>
#include <vector>
#include <string>
#include <iterator>

int main()
{string words[4]={"dd","kk","aa","jj"};

vector<string> svec(words,words+4);

for(vector<string>::iterator it=svec.begin();it!=svec.end();it++)
cout<<*it<<" ";

cout<<endl;
return 0;
}



编译就出现下列问题：

#include <iostream>
#include <vector>
#include <string>
#include <iterator>
using namespace std; // ---> 这是很重要的一句

[madhappy]

1 在后面加上 using namespace std;
2 #include <iostream.h>
#include <vector.h>
#include <string.h>
#include <iterator.h>

[李马]

建议使用
using namespace std;

.h的方法已经被最新的C++标准抛弃了。

虽然抛弃了，但我们还用
