Error In The Script

Question

here is my code i got only 1 error as i fixed most of them i get a error ; expected insert a semicolon at the end. but i get in no way where i should add the last semicolon i managfed to fix 8 errors in the script and updated it to untiy 5 but now i only got 1 single error wich i seems to not solve

here is my code

  int flyingSpeed = 100;
  int; speedChange = 20;
  int; rotationInt = 2;
  
  Update();
  {
  if (Input.GetKeyDown (KeyCode.W));
          {
              flyingSpeed += speedChange;
          }
  
  if (Input.GetKeyDown (KeyCode.S));
          {
              flyingSpeed += -speedChange;
          }
  
  if (Input.GetKey (KeyCode.A));
          {
              transform.RotateAround (transform.position, transform.up, -rotateInt);
          }
  
  if (Input.GetKey (KeyCode.D));
          {
              transform.RotateAround (transform.position, transform.up, rotateInt);
          }
   }

What gjf said, but you're using the line terminator to basically kill your if statements let alone your method called update which should have a return type(like IEnumerable) or void, you have terminators after the type when declaring variables. The code is also incomplete :(

 int flyingSpeed = 100;
 int speedChange = 20; // removed semicolon after the type declaration.
 int rotationInt = 2; // removed semicolon after the type declaration.
   
 void Update()
 {
     if (Input.GetKeyDown (KeyCode.W)) // removed semicolon after if statement
     {
         flyingSpeed += speedChange;
     }
 
     if (Input.GetKeyDown (KeyCode.S)) // removed semicolon after if statement
     {
         flyingSpeed += -speedChange;
     }
 
     if (Input.GetKey (KeyCode.A)) // removed semicolon after if statement
     {
         transform.RotateAround (transform.position, transform.up, -rotateInt);
     }
 
     if (Input.GetKey (KeyCode.D)) // removed semicolon after if statement
     {
         transform.RotateAround (transform.position, transform.up, rotateInt);
     }
 }

If this was actually meant to be unityscript/javascript(based off your comment above) then your script is completely wrong and should look more like:

 var flyingSpeed:int = 100;
 var speedChange:int = 20; // removed semicolon after the type declaration.
 var rotationInt:int = 2; // removed semicolon after the type declaration.
   
 function Update()
 {
     if (Input.GetKeyDown (KeyCode.W)) // removed semicolon after if statement
     {
         flyingSpeed += speedChange;
     }
 
     if (Input.GetKeyDown (KeyCode.S)) // removed semicolon after if statement
     {
         flyingSpeed += -speedChange;
     }
 
     if (Input.GetKey (KeyCode.A)) // removed semicolon after if statement
     {
         transform.RotateAround (transform.position, transform.up, -rotateInt);
     }
 
     if (Input.GetKey (KeyCode.D)) // removed semicolon after if statement
     {
         transform.RotateAround (transform.position, transform.up, rotateInt);
     }
 }
