In your code you are trying cast this pointer instead of variable. You can try the following:

Student(const Student & s)
    : Person(p.getName(), p.getEmailAddress(), p.getBirthDate()), school(0), studentNumber(0) {
    school = new char[strlen(s.school) + 1];
    strcpy_s(school, strlen(s.school) + 1, s.school);
    *const_cast(&studentNumber) = s.studentNumber;
}
