Hi,

You need to refer to datatypes ranges:

The biggest datatype in a x64 is __int64 (equivalent to long long ).
I also recommend you to look at algorithms such as: http://en.wikipedia.org/wiki/Hamming_weight

The algorithms come into great use when you deal with large numbers.
Use an arbitrary precision library like GMP or MPIR. Anyway you will probably ask us to setup it for you, as your computer is broken, right.

__int64 is also available on X86 platform.

If you people hate me,
