I'm using MS Visual C++ 6.0 I'm want to use strings in my application, but I get the error: "error C2065: 'String' : undeclared identifier". I have string.h included in my application, but still is it moaning about the issue undeclared identifier. Can someone help me out please?

string.h contains the C string functions (strcmp, strcat, etc.) The C++ string header is , the string class is called std::string

Now I get this error: "error C2653: 'std' : is not a class or namespace name"

What to include for this?

And as Doggan pointed out you need to let the compiler know which namespace it is in. (Unless you using "using namespace std;" which is generally considered bad style.)

Whenever I trying to place "using namespace std;" I says: "error C2871: 'std' : does not exist or is not a namespace"

#include

std::string myStringYay;

or...

#include

using namespace std;

string myStringYay;
