Auto Fill 6 cells based of of text in one other cell

I am looking for a VB code to perform the following:

If text in Column C is "DDC" or "VOID".... I would like column K, M, O, Q, S and T to auto populate with the same wording and leave blank if any other text is in column C or if it is blank. A formula will not work for this because of the end use of this spreadsheet.

C K M O Q S T
DDC DDC DDC DDC DDC D DDC
VOID VOID VOID VOID VOID V VOID

so it would look similar to the above but in excel obviously.

Please help!

Thanks that works!

Can you add the coding that makes the macro run as cells are updated?
