[C + +] base class object as a function parameter (Assignment compatibility rule)

Programming to handle the basic situation of teachers. Requirements:

1, define a "person" class, used to store and deal with the name, gender, age, member functions of the self-defined;

2, the definition of "teacher" category, the public inherits "Person" class to store the teacher's school, the major, education, degree, title, seniority, etc., member functions of the self-determined.

3, processing procedures, mainly include:

⑴ display Name, gender, age function: Displays the name , gender, age of the person object, and displays the name, gender, and age of the teacher object (referenced by person as a parameter) ；

⑵ shows the function of Teacher's college, major, degree, degree, title and seniority;

⑶main () function: Define persor object and teacher object Separately, enter different object related values, call member function to set the value of object, call display function to display corresponding value.
