c++/cli caret^ Vs. Pointer*?

问题:

I've programming for a long time in C and in C#, I thought moving to C++ would be smooth...
anyway, I've seen the use of caret but I don't understand the meaning of it.

what's the different between:

std::string *st1;

to

String::string ^st2;

Thanks!

回答1:

The caret is specific to C++/CLI, Microsoft's .NET version of C++, where it is the managed equivalent of a pointer.

It is not actually part of standard C++, so unless you truly mean to use .NET, don't use it.

回答2:

String::string ^st2

is not a standard ANSI C++ syntax!
