Print Affinity Mask?

i want to print out affinitiy mask and how which CPUs are not enabled if there were turn off via task manager. 

here the sample code it does show when a core is disable but it will still list as 

1 2 3 4 5 6.. not like if CPU 2 gets turn off it show be 1 3 4 5 6

    HANDLE process = GetCurrentProcess();    DWORD_PTR processAffinityMask;    DWORD_PTR systemAffinityMask;    if (!GetProcessAffinityMask(process, &processAffinityMask, &systemAffinityMask))        return -1;    DWORD_PTR mask=0x1;    for (int bit=0, currentCore=1; bit < 64; bit++)    {        if (mask & processAffinityMask)        {        printf("Core %d \n", currentCore);            currentCore++;        }        mask = mask << 1;    }
