C in CDX means one side of the plywood is of grade C, and the other is of grade D. Not that it matters a lot in the tasks they are meant for, but usually, the part of better grade is used on the more visible side while the one of lower grade is used on the less hidden side.

X stands for exposure, which is the type of glue used to bind the plywood together. However, note that the grading is not about the quality but the appearance of the wood because CDX is pretty strong and resistant to damage. Besides, the tasks for which CDX is meant for requires more quality than good appearance.
