Week 12 - task 2- shoulder to shoulder cadres

【 subject 】（ The teaching material P394 exercises 9） Defining the Teacher( Teachers' ) Classes and Cadre（ Cadres ） class , A new class is derived from these two classes by means of multiple inheritance Teacher_Cadre（ Teachers and cadres ）. requirement ：
（1） Include names in both base classes 、 Age 、 Gender 、 Address 、 Telephone and other data members .
（2） stay Teacher Class also contains data members title( The title ), stay Cadre Class also contains data members post（ position ）, stay Teacher_Cadre Class also contains data members wages( Wages ).
（3） For names in two base classes 、 Age 、 Gender 、 Address 、 Telephone and other data members use the same name , When referring to these data members , Specify scope .
（4） Declare member functions in the body of the class , Define member functions outside the class .
（5） In derived classes Teacher_Cadre Member function of show Call in Teacher Class display function , Export name 、 Age 、 Gender 、 The title 、 Address 、 Telephone , And then use cout Statement output job and salary .

（ In some universities , Teachers with administrative positions , be called “ Shoulder to shoulder ”. I did , I can't pick , I dropped one end , It's what it is now .）

【 analysis 】 The key to this problem is to have data members with the same name in two base classes , The ambiguity caused by multiple inheritance arises . In a derived class , Need to pass through “ Class name :: Member name " Form solution . This is one way to solve this kind of problem .
