Why this typedef not working

[John theKing]

I am getting many errors in the following code: #ifdef _UNICODE typedef std::wcout _tcout; #else typedef std::cout _tcout; #endif But i am not getting any error in this code: #ifdef _UNICODE typedef std::wstring _tstring; #else typedef std::string _tstring; #endif Can anyone tell me what is the problem in the first case, because i am getting 8 errors. I am copying first error below: c:\documents and settings\tstring.h(22) : error C2146: syntax error : missing ';' before identifier '_tcout' Yes, Yes i am including all header files like iostream e.t.c

didn't you forget an #include <iostream> somewhere ? ~RaGE();

std::cout is not a type, but an object, so you cannot use it in a typedef declaration. It is as if you write:

int a;
typedef a b; //no way!
