use unicode or multiple char

[ylxin1993]

in vs2010, the default encoding is unicode, but my book is a little old, I have to add

L

before my string, and I know nothing about unicode, I want to know if there's any book about unicode, because my book sometime use "string" + "stirng", but I don't know how to connect 2 string in unicode.

can you also introduce me some web for beginner to know unicode?

You could disable Unicode settings in VS2010 really easy by adding this at the very beginning:

#undef UNICODE
#undef _UNICODE 

Or just go to Project Properties - General - Project Defaults - Character Set and change to "Not Set".
Unicode means all char occurences will be replaced with wchar_t.
