Hi Manjunath,
Despite the ret variable being defined as 32-bit unsigned integer, the
compiler might do the calculations per default in 16-bit, thus getting
an incorrect result. Can you try to add the letter "L" behind the
numeric constants to force the compiler to do the calculations in
32-bits and see whether this works?
Cheers,
Urs
