//类操作函数,基本上都是复制构造函数
WCHAR* getPhoneBrand(const CPhone& phone); //获得电话的品牌

char* getPhoneNumber(const CPhone& phone); //获得电话号码
bool isSupport3G(const CPhone& phone); //查询是否支持3G
char* changePhoneNumber(char *newPhoneNumber);//更改电话号码,该函数调用后，必须显式释放申请的内存
void displayPhoneBrand(void); //显示电话品牌
void displayPhonePrice(void); //显示电话价格
void displayPhoneNumber(void);//显示电话号码
private:

unsigned int m_price; //电话价格
