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

Programming to handle the basic situation of teachers.

Requirements:

1. Define a "person" class. Used to store and process the person's name, gender, age, member function 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, as well as the name, gender, and age of the teacher object (referencing the object as a person) ；

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

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