VC++2010 no support RAW STRING? --identifier is undefined.

[q1670741824]

My code is below, is that my gramma error or i have to add some #include?

cout << R"(where is the problem?)";

the hint is :
identifier is undefined.
expected a ';'

VC++ 2010 has no support for raw string literals. (VC++ 2012 CTP or VC++2013 is required.)
