I edited your post to remove some superfluous formatting.

The ? and : characters together are the "ternary operator." It's basically a shorthand way of writing "if/then". Another way to write exactly the same thing would be

if (theDX > MAX_V)
   theDX = MAX_V
else
   theDX = theDX;

Of course, written out like this, the "else" part is redundant.
