Question

For the following program determine if it will compile properly and why and determine what the program does. int JoyStick_X = A0; int JoyStick_Y = A1; int JoyStick_Z = 3; void setup () {pinMode (JoyStick_X, INPUT); pinMode (JoyStick_Y, INPUT); pinMode (JoyStickZ, INPUT_PULLUP); Serial.begin (9600);} void loop () {int x, y, z; x = analogRead (JoyStick_X) y = analogRead (JoyStick_Y); z = digitalRead (JoyStick_Z); Serial.print (x, DEC); Serial.print (", "); Serial.print (y, DEC); Serial.print (", "); Serial.println (z, DEC); delay (100);
