I have just started learning c++, in c++ programming some times I have to use ^ after string for example 

string^ abc;

And sometimes there is no need of ^ and we can write our line as

string abc;

This confuse me a lot, I don't know when to use ^ and when to ignore it. I know its a foolish question but I desperately need to clear my concept of ^ so please tell me when to use and when to ignore ^ in c++.

    To make this a bit more clear, `string^` is part of C++/CLI, a C++ extension for the .NET runtime. It is not part of Standard C++. – filmor Jul 04 '14 at 04:51
  • Just be aware that this isn't something in standard C++, it's an artifact of Microsoft's attempt to integrate it with .NET. – Mark Ransom Jul 04 '14 at 04:52
