我正在尝试为观察者模式开发 C++ 程序，但我收到了这些错误。这是我的 CPP 代码，我不断收到错误消息：“声明终止不正确”！预先感谢帮助我，我很绝望。

#include<conio.h>
class Subject{
public : virtual ~Subject();
virtual float attach()=0;
virtual int notify()=0;
};
class Observer{
public : virtual ~Observer();
virtual void update(int type, float amount, float bal)=0;
};
class Account : public Subject

You are missing a ;at the end of the class declaration. Correct:
您;在类声明的末尾缺少一个。正确的：
class Foo
{
/*...*/
};
In C++, mainshould be a free function, the obptclass is wrong.
在C++，main应该是自由函数，obpt类错了。
int main()
{
/* ... */
}

The error message you are receiving is coming from the compiler. It is stating that a declaration statement has not been ended correctly.
您收到的错误消息来自编译器。它表明声明语句没有正确结束。
Somewhere in your code you are missing a semi-colon ; perhaps at the end of a class declaration or after a variable is defined.
在您的代码中，您缺少一个分号；可能在类声明的末尾或在定义变量之后。
Without seeing your code, there is no way for me to pinpoint the problem, but the error message should take you to the line if you double click it!
没有看到您的代码，我无法查明问题，但是如果您双击它，错误消息应该会将您带到该行！
