using namespace std;
void main()
{
string str="aa";
cout<<str;
}

哎呀 你的头文件用错了 应该用新版头文件#include<iostream>

#include <string>
#include<iostream>
using namespace std;
void main()
{
string str="aa";
cout<<str<<endl;
}

#include<iostream>

头文件用错
#include<iostream>

#include <string>
#include<iostream>
using namespace std;
void main()
{
string str="aa";
cout<<str;
}

同一楼,
#include <string>
#include<iostream>
using namespace std;
void main()
{
string str="aa";
cout<<str;
}
