Trouble With Variables

I should start off by saying I started this season with no experience in programming and thus learned all I know form the FRC website so please try to answer in easy to understand terms if you can. Anyway, I am trying to make a varying shooter for shooting balls and I use the variable x and when I hit the button it doesn't work. I have tried using a basic number value and it does so it has to be an issue with the variable. Here is the code:
#include <WPILib.h>
/**
* This is a demo program showing the use of the RobotDrive class.
* The SampleRobot class is the base of a robot application that will automatically call your
* Autonomous and OperatorControl methods at the right time as controlled by the switches on
* the driver station or the field controls.
*
* WARNING: While it may look like a good choice to use for your code if you're inexperienced,
* don't. Unless you know what you are doing, complex code will be much more difficult under
* this system. Use IterativeRobot or Command-Based instead if you're new.
*/
class Robot: public frc::SampleRobot {
frc::RobotDrive myRobot { 0, 1 }; // robot drive system
frc::Joystick stick { 0 }; // only joystick
public:
Robot() {
myRobot.SetExpiration(0.1);
}

void OperatorControl() {
int x = .50;
Talon *exampleTalon = new Talon(4);
int buttonValue0 = stick.GetRawButton(1);
int buttonValue1 = stick.GetRawButton(2);
int buttonValue2 = stick.GetRawButton(3);
while (IsOperatorControl() && IsEnabled()) {
buttonValue0 = stick.GetRawButton(1);
buttonValue1 = stick.GetRawButton(2);
buttonValue2 = stick.GetRawButton(3);
myRobot.ArcadeDrive(stick); // drive with arcade style (use right stick)
frc::Wait(0.005); // wait for a motor update time
if (x <= 1.0 and buttonValue0 == 1)
{
x = x + 0.005;
//frc::Wait(0.005);
}
if (x >= 0.0 and buttonValue1 == 1)
{
x = x - 0.005;
//frc::Wait(0.005);
}
if(buttonValue2 == 1)
{
exampleTalon->Set(x);
}
}
}
};
START_ROBOT_CLASS(Robot)
Any help would be greatly appreciated.
