Thanks in advance!

as said before, in the Arduino path, you look for hardware\cores\arduino
it has all the sourcecode for the individual arduino functions like digitalWrite, pinMode, etc. so if you fancy taking a look, that's where you'll need to be.

I see functions like this one,

void Print::println(const char c[]){
..
}

in this file {Arduino Path}\hardware\cores\arduino\Print.cpp

what this mean void Print::println? it is not usual to see this, i think.

It means "println" is a member of the class "Print", and is a "void" (i.e. it doesn't return a value) function.
That's C++, and perfectly usual.

You'll see that that there are different versions of the functions, distinguished only by their parameter types. This is called "overloading"

Ok, thanks, i never seen C++ source code, only C, that is why i couldn't understand.
