    Use runtime_error and explicit

    class BadLengthException : public runtime_error {
public:
    explicit BadLengthException(int n) : runtime_error(to_string(n)) {}
};

    class BadLengthException{ private: int n; //Length

    public:
    BadLengthException(int errornumber){
        n = errornumber; //
    }
     int what(){
        return n;
    };
