Programming gyro, noob programmer

[Lawlhwut]

#include "WPILib.h"
class RobotDemo : public SimpleRobot
{
static const float Kp = 0.03;
RobotDrive myRobot;
Gyro gyro;

public:
RobotDemo(void):
myRobot(1, 2), // these must be initialized in the same order
gyro (1)
{
myRobot.SetExpiration(0.1);
}

void Autonomous(void) {
gyro.Reset();
while (IsAutonomous())
DriverStationLCD *screen = DriverStationLCD::GetInstance();
{
float angle = gyro.GetAngle(); // current heading (0 = target)
myRobot.Drive(-1.0, -angle / 30.0); // proportionally drive in a straight line
Wait(0.004);
screen->PrintfLine(DriverStationLCD::kUser_Line1,"KimpeeA ngle", gyro.GetAngle());
screen->UpdateLCD();
Wait(0.1);
}
myRobot.Drive(0.0, 0.0);

};
START_ROBOT_CLASS(RobotDemo);

This is the program i'm writing for the gyro. It is supposed to get the angle from the gyro and print it on the driverstation dashboard. But it is not compiling. Some fixes and basic syntax/structure info pl0x.
