C++ Tank Drive Help

[MI6]

Please help with the errors and how to use a xbox controller with it!

I am getting a few errors with my code!
- Error: expected identifier before numeric constant
- Error: ISO C++ forbids declarations of parameter with no type
- Error: expected ',' or '...' before numeric constant
-Syntax Error


Code:

#include "WPILib.h"

class RobotDemo : public SimpleRobot
{
RobotDrive drivetrain(1, 2);
Joystick leftStick(1);
Joystick rightStick(2);

public:
RobotDemo()
{
GetWatchdog().SetEnabled(false);
}
void Autonomous()
{

}
void OperatorControl()
{
while (1) // loop forever
{
drive.Tank(leftStick, rightStick); // drive with the joysticks
Wait(0.005);
}
}
};

START_ROBOT_CLASS(RobotDemo);
