您可以继承std :: logic_error，并以这种方式定义错误消息：

You can inherit from std::logic_error, and define your error message that way:

class NotImplementedException : public std::logic_error
{
public:
    virtual char const * what() const { return "Function not yet implemented."; }
};

我认为这样做会使异常更加明确，如果这实际上是一种可能性。
引用std :: logic_error：

I think doing it this way makes catching the exception more explicit if that's actually a possibility. Reference to std::logic_error: http://www.cplusplus.com/reference/stdexcept/logic_error/
