You can find the vendor identifier with CPUID. The same mechanism can be used to find out what features the CPU supports, which is normally more useful than merely knowing the vendor, obviously it depends on what you want.
As someone already mentioned, the CPUID instruction gives you this information. It may be called using compiler intrinsics (#include <intrin.h>) on the Microsoft compiler. See here for fuller documentation. Pay attention to the EAX=0 function (Get Manufacturer ID).
It appears that the same information may be found in the Registry at HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0\VendorIdentifier
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Assuming you mean 1 * 2 * 3 * ... * 998 *999 * 1000, then I have bad news for you. The result when written out has 2568 digits in all. That is far more than even a 64 bit integer can express. So, either you have misunderstood your assignment, or you are supposed to be working with some arbitrary precision library. In either case, we don't do homework for you. If you have tried something and are stuck, we're happy to help point you in the right direction.
