Arduino: "error: expected unqualified-id before '{' token"

Question

当我尝试编译这段代码时，我得到了标题中的错误消息。我对此很陌生，不确定是否有什么事情完全超出了我的理解范围。这段代码只是为了测试我试图用 arduino 自动驾驶的 RC 汽车上的接线。我以前在这里作为问题看到过此错误消息，但我找不到将那里的解决方案应用到我的代码的方法。我已经尝试查看所有括号并确保它们彼此配对（例如 {}，而不是 {{ 或 }} 或 }{）。我希望能够在感恩节假期前解决此问题，因此非常感谢您的帮助。

int driveneg = 9;
int drivepos = 5;   /*this shows all my variables*/
int steeringneg = 6;
int steeringpos = 3;

byte speed =255;

    void setup ();
    {
        pinMode (steeringneg, OUTPUT); 
        pinMode (steeringpos, OUTPUT); /*setting the motors to output*/
        pinMode (driveneg, OUTPUT);
        pinMode (drivepos, OUTPUT);
    }
    void loop ();
    {
        forward();
        delay (2000);
        backward();
        delay (2000);
    }
    void backward();
    {
        analogWrite (9,0);
        analogWrite (5, speed);/*defines forward and backward functions*/
        analogWrite (6, 0);
        analogWrite (3, speed);
    }
    void forward();
    {
        analogWrite (9, speed);
        analogWrite (5, 0);
        analogWrite (6, speed);
        analogWrite (3, 0);
    }

Answer 1

去掉函数括号后的分号（;），像这样：

void setup ()
{
    ...
}

Arduino: "error: expected unqualified-id before '{' token"
