Function declarations


Without a function[2] declaration, a system[3] does not know what a function is supposed to do. Some systems have function declarations[1] built into their libraries, but if you create a new function, you have to write a function declaration in order to be able to use it. If the outcome[4] of your function is supposed to be a cake, a function declaration is much like a recipe for the computer to follow.
