std::string IO

Code:

---

#include<iostream>
int main()
{
 std::string szName;
 std::cin >> szName;
 std::cout << szName << std::endl;
 return 0;
}

---

This code, while compilation gives the following error.

What may be the problem?

Thanks.

Yiu need to:

Code:

---

#include <string>

---

Thanks. So is the intellisence independant of the headers we have included?

Intellisense is not C++.

If you're going to use std::string, then you must include the <string> header. Don't solely rely on third-party tools such as Intellisense to determine proper C++ coding.

To be fair that's a rather silly error message. "std::string not defined" would have been more intuitive.

I think that std::string is forward declared within the stream headers, so it is difficult for the compiler to emit such an error.

Ah yes, and such an operator could have been declared using just such a forward declaration, good point.
