Im relativley new to al this.
What is the best way to segment a library please.
Im familiar with using functions but wondering when i should put them into libraries.
I have kelly and pohl book on c, but it has little in the way of library examples
I have noticed that when a function calls another function , the calling function has to be located after the called one for the compiler to find the reference.
Is there a way around this please, - public declaration ?
The usual way is to put the function prototypes in a header file.

Not if you use the Arduino IDE, because it creates the function prototypes behind the scenes and puts them near the start of the program for you.
I think you need prototypes in libraries though... And also if you break a sketch up
into lots of .h files those .h files you might need them.
