// 2014 Dec COMP2396 Question 1a)
/* The problem is, the array of students were initialized,
* But the individual student objects were not initialized.
* A fix would be add "cs0396[0] = new Student();" and "cs0396[1] = new Student();"
* before assigning values to the student objects.
* The output would be
* Kevin 12345
* Haoyuan 67890
