HW13: Linked List

1. Consider the class definition of CList, which stores a linked list.
2. Inspect the construction, and make sure you understand how it initialize a linked list.
3. Combine it with main.cpp and try to compile. The Print() function will display the value of nodes in the list sequentially.
4. Inspect the push_front() function, which inserts a new node in front of the list.
5. Try to design a push_back() function, which appends a new node at the end of the list.
6. Furthermore, overload the >> operator so that you can print out the list with a statement like cout << myList;
   Remember that you must declare the >> operator as a friend function of your CList class.
7. Test your class with the following main() function.

   int main()
   {
     CList a(3);
     a.push_front(5);
     a.push_front(7);
     a.push_back(1);
     a.Print();
     cout << a;
     return 0;
   }
   

8. Submit the class definition file with filename "hw13-your_stu_id-list.h"
