(1), define a personnel class person, including member variables: number, name, gender, and the member function for inputting input and outputting output;
(2), on this basis, derived from the Student class student (add a member variable: score) and teacher class teacher (add a member variable: seniority);
(3), the student class and the teacher class respectively has the input inputs, outputs the output the member function;
Add an overload of the + symbol to the people class to achieve the following:
(4) The two person class is added, the result is still a personnel class, and the number, name, gender, respectively, the string is added.
(5), add the main function to test the above definition.
