彩票兑奖程序

//各种彩票类的父类
class Ticket
{
protected:
    std::vector<sector> data_;//经过解析的彩票格式化数据
public:
    Ticket(std::string ticket_str);
    Ticket(){}
    sector getSector(int index) const;//get

    bool isMultiple();//复式？
    virtual size_t firstLength()=0;//前区长度
    virtual size_t secondLength()=0;//后区长度
    virtual void parse(std::string s);//接收字符串型格式,解析
    virtual boost::shared_ptr<Ticket>  CreateSafeInstance()=0;    virtual std::vector<sector>& getData(boost::shared_ptr<Ticket> ticket)=0;//把复式解析成单式,智能指针返回


    virtual std::ostream& formatedCout(std::ostream& o) const{return o<<std::setw(2)<<std::setfill('0');}
    virtual const char* sep_char() const{return " ";}

    std::vector<boost::shared_ptr<Ticket>  > getTickets();

    std::string ticketId;

    friend std::ostream &operator<<(std::ostream &o,const Ticket &t);
};


超级大乐透

class BigHappyTicket: public  Ticket
{
public:
BigHappyTicket(std::string ticket_str);
BigHappyTicket(){}
virtual size_t firstLength(){return 5;}
virtual size_t secondLength(){return 2;}
virtual boost::shared_ptr<Ticket>  CreateSafeInstance();
virtual std::vector<sector>& getData(boost::shared_ptr<Ticket> ticket);

};


双色球

class Color2Ticket: public  Ticket
{
public:
Color2Ticket(std::string ticket_str);
Color2Ticket(){}
virtual size_t firstLength(){return 6;}
virtual size_t secondLength(){return 1;}
virtual boost::shared_ptr<Ticket>  CreateSafeInstance();
virtual std::vector<sector>& getData(boost::shared_ptr<Ticket> ticket);


};
