The value of x++ is what x was before
The value of ++x is what x is after

Both still increment

Also ya, passing structs by value makes a copy. If you want to modify the original, you need to pass a pointer to it

Best way I think of it: in Java, every object (non-primative) is passed by a pointer (sort of)
