Clear Contents Based On Criteria

I need some code that will clear the contents of a Row Range(C:T) if either of the contents of cells X and Y = "E"

The code needs to look at cells X17 and Y17 and continue looking until it gets to X216 and Y216

So - If X = E but Y does not, then the row range C:T must be cleared.
If Y = E but X does not, then the row range C:T must be cleared
If both X and Y = E, then the row range C:T must be cleared

If the letter E does not exist in either X or Y, then the row must be left alone
