I am currently using Visual Studio 2008 Express edition on Windows 7, 64 bit.

If I code and compile a program using 64 bit data types such as __int64 or LONGLONG, will the program be able to run on Windows XP or windows 2000? Or on 32 bit CPUs?

__int64 and LONGLONG would work in 32 versions of Windows as well.
