Yes... :) If you look into the code of CString you will get the answer.

No need to guess: CString is a ATL/MFC class [^]. A class instance is an object. :)

then why the size of CString is 4..?

The size of a class object is the sum of size of all the non static members. If you check the CString class (as I told before) you can find only one member inside it. ie., LPTSTR m_pchData;

CString is an object which has some methods as GetLength() which will return the lenght of the incorporated string. :doh: Plaese clarify your question... :sigh:
