Item 4-pointers to student classes

Design a student class student, the data members include the number (num) and the score (score), the member function according to the needs of the self-design (recommended to be equipped with the required set, get function, as well as the necessary input or output, the given code can also find the need for member functions of the thread). In the main function, to do this:
Set up an array of objects that, through initialization, sets the data for 5 students, requiring:
The pointer points to the first element of the array, outputting the information of the 1th, 3, 5 students;

Design a function int max (Student *arr), use a pointer to the object as a function parameter, and in the Max function find the top 5 students, and return the value of their study number.
