Testing the INT_DLLIST Instantiation:

This tests the int instantiation:

  {
  int input1[10] = {1,2,3,4,5,11,7,8,9,10};
  int input2[6] = {10,20,30,40,50,60};
  int c1 = 11;
  int c2 = 30;
  int c3 = 17;
  int c4 = 10;
  int c5 = 3;
  char *name[] = {"intQaitlin","intQuinn","intJim","intPauli"};

  cout << "Instantiating List Qaitlin" << endl;
  INT_DLLIST Qaitlin(name[0]);

  cout << endl << "Building Qaitlin List" << endl;
  Qaitlin.build_list(input1,size1);
  cout << "Qaitlin has " << Qaitlin.get_number_elements() << " elements";
  cout << endl;
  cout << endl << "Qaitlin = " << endl << Qaitlin << endl;

  cout << endl << "Delete the element " << c1 << endl;
  Qaitlin.delete_element(c1);
  cout << endl << "Qaitlin = " << endl << Qaitlin << endl;

  cout << endl << "Insert element " << c2 << "after " 
       << c5 << endl;
  Qaitlin.insert_after(c5,c2);
  cout << endl << "Qaitlin = " << Qaitlin;

  cout << endl << "Insert element " << c4 << "before " 
       << c3 << endl;
  Qaitlin.insert_before(c3,c4);
  cout << endl << "Qaitlin = " << Qaitlin;
  cout << "Qaitlin has " << Qaitlin.get_number_elements() << " elements";

  cout << endl << "Sort the list Qaitlin." << endl;
  Qaitlin.mergesort();
  cout << endl << Qaitlin << endl;

  cout << "Copy Constructor Test: Copy Qaitlin into Quinn:" << endl;
  INT_DLLIST Quinn = Qaitlin;
  cout << "Quinn = " << Quinn;

  cout << "Instantiating List Quinn" << endl;
  INT_DLLIST Jim(name[2]);

  cout << endl << "Building Jim List" << endl;
  Jim.build_list(input2,size2);
  cout << "Jim has " << Jim.get_number_elements() << " elements";
  cout << endl;
  cout << endl << "Jim = " << endl << Quinn << endl;

  cout << endl << "Overloaded Equal Test: Jim = Qaitlin" << endl;
  Jim = Qaitlin;
  cout << endl << "Jim = " << endl << Quinn << endl;

  cout << "Test Overloaded Input Operator: " << endl;
  INT_DLLIST Pauli(name[3]);
  cin >> Pauli;
  cout << "Pauli = " << Pauli;

  return 0;
  }

The corresponding output is:

Instantiating List Qaitlin

Building Qaitlin List
Qaitlin has 10 elements

Qaitlin = 
1<-->2<-->3<-->4<-->5<-->11<-->7<-->8<-->9<-->10.

Delete the element 11

Qaitlin = 
1<-->2<-->3<-->4<-->5<-->7<-->8<-->9<-->10.

Insert element 30after 3

Qaitlin = 1<-->2<-->3<-->30<-->4<-->5<-->7<-->8<-->9<-->10.

Insert element 10before 17
The element 17 is not in the list.
17 is not in the list, so do not insert.

Qaitlin = 1<-->2<-->3<-->30<-->4<-->5<-->7<-->8<-->9<-->10.

Qaitlin has 10 elements
Sort the list Qaitlin.

1<-->2<-->3<-->4<-->5<-->7<-->8<-->9<-->10<-->30.

Copy Constructor Test: Copy Qaitlin into Quinn:
Quinn = 1<-->2<-->3<-->4<-->5<-->7<-->8<-->9<-->10<-->30.

Instantiating List Quinn

Building Jim List
Jim has 6 elements

Jim = 
1<-->2<-->3<-->4<-->5<-->7<-->8<-->9<-->10<-->30.

Overloaded Equal Test: Jim = Qaitlin

Jim = 
1<-->2<-->3<-->4<-->5<-->7<-->8<-->9<-->10<-->30.

Test Overloaded Input Operator: 
Please Enter the element which terminates input:
999
12 35 -76 89 999
Pauli = 12<-->35<-->-76<-->89.
