/* includes:
 * stdio.h & stdlib.h are included by default (for printf and LARGE_INTEGER.QuadPart (long long) use %lld or %016llx).
 * inttypes.h, stdbool.h & string.h included for various type support and utilities.
 * conio.h is included for windows(dos) console input functions.
 * windows.h is needed for various timer functions (GetTickCount(), QueryPerformanceFrequency(), QueryPerformanceCounter())
