You do not have to use prototypes; so long as you define the function before you use it, it will work. In addition to Bazzy's words, if you ever want to use a function that you did not write and are not going to be compiling yourself (which I expect is very, very often), the compiler must still know what will be passed in and what will be returned.

Even if the surface is not wiped, the resulting faint white stain will still fade away as it dries.
