c++ - Using std::string?

Hello everyone! :-D
OK, here be my code:

-----------------
#include <stdlib.h>
#include <string.h>

int main()
{
string hello("Hellawz!!1");
}
-----------------

And here's my command line:

dmc -mtd -IC:\dm\stlport\stlport dost.cpp

This is what I get on compile:

-----------------
Z:\dost>dmc -mtd -IC:\dm\stlport\stlport dost.cpp
string hello("Hellawz!!1");
^
dost.cpp(6) : Error: undefined identifier 'string'
string hello("Hellawz!!1");
^
dost.cpp(6) : Warning 6: value of expression is not used
--- errorlevel 1

Z:\dost>
-----------------

I tried using std::string, using namespace std, nothing worked... anyone know
how to fix it? Thanks! ;-)

string.h is for C-string manipulation functions, such as
strcpy, strcmp, etc.

To get C++ stl string use string (note without the .h).
E.g:

#include <string>
using std::string;
int main()
{
    string hello("Hellawz!!1");
}

Do you know how I can fix them? Thanks very much! ;-)

Wait a minute... I don't get any of that if I remove the "-mtd" from the command
line... I need this program to work on pure MS-DOS... do you know how to fix it?
Thanks! ;-)

The STL doesn't work under MS-DOS. For one thing, it's a little too large to
work with the 'tiny' (-mt) memory model, where code+data needs to fit in
64K. You'll need to stick with the functionality in the C headers.

Blah, that stinks! :-(
Thanks though! ;-)
