String ^ declaration in C ++

Question

As far as I know, a C ++ line declaration follows a form:

std::string param;

I went through the code and realized that the line declaration is as follows:

System::String^ param;

Can anyone share the light with this declaration ?! Is this a Microsoft Visual C ++ string declaration or a special library that provides another alternative to using a C ++ string.

This is the C ++ / CLI syntax of handle to an object on a managed heap.
