Hi Gaurav, You could do this... q = 4294967295U
Or you could use -std=iso9899:1999 (perhaps with -pedantic) for the compiler to produce an error. Assuming you are using GCC 4.x. Or if you *want* to allow that, you could do this... -std=gnu99 I'm guessing as to which version of GCC you are using, and what command line options you used to compile with, and your platform's architecture. HTH, --Eljay
