I want to initialize an array in global with a particular element as variable

unsigned char SlotID;
unsigned char array[]= {SlotID,0x8,0x5,0x3};
main()
{
  slotID= getslotid();// some function to get the value of slot id

}

I am getting error while compiling that slotID is not constant. Please tell what do I need to do. SlotID value I will retrieve from getslotid function and accordingly I pass array value to some other function.

want to use array in other modules as well – user249520 Jan 28 '16 at 07:45
What do you want to achieve this way actually? – πάντα ῥεῖ Jan 28 '16 at 07:46
You're not initializing `SlotID` explicitly, so use `unsigned char array[]= {0x0,0x8,0x5,0x3};` – Sourav Ghosh Jan 28 '16 at 07:46
actually i am working on a system which reads the slotid from the hardware and then it communicates with other module where slotid is the header. It will be different for different cards and hence i want to keep it as a variable – user249520 Jan 28 '16 at 07:53
@sourav i want to get the value of SlotID in runtime and then pass the array[] to a diff module – user249520 Jan 28 '16 at 07:54
@user249520 Ask a new question please. – 2501 Jan 28 '16 at 08:02
@user249520 Once after initialization the array won't be changed anyway. You cannot do it this way. – πάντα ῥεῖ Jan 28 '16 at 08:19
thanks. got it. i have to do a diff way – user249520 Jan 28 '16 at 09:38
