Where are strings?

I can include all 3 of the following headers:

Code:

#include <string>

#include <string.h>

#include <cstring>

Yet declarations of

Code:

String j;

and

Code:

string j;

both get rejected by the compiler, stating that, "string is used as a type, but is not defined as a type." when in a class, and "string undeclared (first use this function)" elsewhere. I'm using Xcode 1.2 (OSX 10.3.9). What should I do?

Code:

#include <string>

std::string s;

Also possible:

Code:

#include <string>

using std::string;

string s;

Also possible, but not recommended:

Code:

#include <string>

using namespace std;

string s;

To clarify: all of the STL is in the std:: namespace. Hence, you have to specify that you want std::string (which is the proper name) in any of the three ways mentioned above. Some compilers pull in the std:: namespace silently, but it's wrong and dangerous.
