Array Problems: Possible<stdio.h>

[Alex Wijtowych]

Hello, I would appreciate if anyone can help me out with this arrray statement. I'm not sure if I have to put it in a function or import a header library so I can use an array. Here is my code, also it is available to anyone who wants to use it. It uses one joystick to drive a a 2 wheel drive bot with the wheels in the centre, like a tank. It also solves the problem of having the joystick go forward and the bot turn and vice versa.

/*Alex Wijtowych's Little addition to the code to make a dual axis drive system with a smoother control!!!*/
/*Let PWM 09 represent the right wheel of the bot and PWM 10 represent the left wheel of the bot*/
