C++中运行时类型信息(RTTI)及动态强制类型转换

核心提示：//typeid函数定义在typeinfo头文件中，typeid()接收一个类型对象，C++中运行时类型信息(RTTI)及动态强制类型转换(2)，此函数返回一个typeinfo对象，调用typeinfo对象的name方法，即可以打印传入的类型对象的具体类型信息cout<<"Now Object =

//typeid函数定义在typeinfo头文件中，typeid()接收一个类型对象，此函数返回一个typeinfo对象，调用typeinfo对象的name方法，即可以打印传入的类型对象的具体类型信息
cout<<"Now Object = "<<typeid(*employee[i]).name()<<"is destrctor !!!"<<endl;//返回相应的typeinfo对象
delete employee[i];//动态释放相应内存
}
}
void ptrPrint(const Employee const *employee){//指向常量数据的常量指针
employee->print();
cout<<"\nearning = "<<employee->earning()<<endl;//静态调用所有方法employee->earning();
}

程序执行的结果：
CommsionEmployee: bai, sunwu
socialNumber : 123456789 SalaryRate = 0.50, sailSalary = 10000.00
Earning = 5000.00
Old baseCommsionEmployee sala = 10000.00//此处动态的识别了BaseCommsionEmployee对象类型，动态强制类型转换，并修改了相应的信息。
After increame 10% ,Now baseCommsionEmployee baseSala = 11000.00
