Goal: Design a small student management system. Step 1: 1, for a student class, as the core of the whole system, we hope that this class will include the basic information of the students are: student's name (strName), student id (strNumber), gender (strSex), birth time (strBirthday), professional (strSpeciality), domicile of origin (strAddress), etc., required when building students object to provide at least your name and student id. 2. As an example of student class, we hope to modify the different information of these students by setting up the set get method. 3. Print the information by rewriting the toString() method. Step 2: 4. When constructing student objects, only name information can be provided, and the student id should be processed within the students' class. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Step 3: 5. Students may elect some of them as student cadres, so these students can construct a new class by inheritance. Student cadre is more than student a function (strDuty) field, use polymorphism to realize the class cadre information printing.
