The following is a partial decleration of the SeqList class. Use it with parts A to C.

class SeqList
{
private:
  .....
  public:
   // constructor
  SeqList(void);

  //List access methods
  int ListSize(void) const;
  DataType GetData(int pos) const;

  //List modification methods.
  void Insert(const DataType& item);
  void Delete(const DataType& item);
  DataType DeleteFront(void);
};

The main program calls the function PrintList that outputs the elements in the list. Trace the code and give the outputs #1 to #5

#include <iostream.h>

typedef int DataType;
#include "aseqlist.h"

void PrintList const SeqList &L
{
  for (int i=0;i<L.ListSize();i++)
    cout <<L.GetData(i)<<" ";
  cout << endl;
}

void main(void)
{
  SeqList L;

  L.Insert(5);
  L.Insert(10);
  L.Insert(1);
  L.Insert(15);
  PrintList(L);            //Output #1 ____
  if (L.GetData(1)==10)
    L.DeleteFront();
  PrintList(L);           //Output #2 ____
  L.Insert(25);
  L.Delete(1);
  cout << L.ListSize()<< endl; // Output #3 ____.

  PrintList(L);          //Output #4 ____
  while (!L.ListEmpty())
    {
      cout << L.GetData(0)<<endl;
      L.Delete(L.GetData(0));
    }
}                        // Output #5 ____

In the main program determine Output #5 if the while loop were changed to

while(!L.ListEmpty())
{
	cout <<L.GetData(L.ListSize()-1)<< endl;
	L.DeleteFront();
}
//OutPut #5

In object-oriented design, first develop the subprograms that will be used by the main program and place them as methods in a series of class declarations.
(a) True (b) False.
