CSE225L Lab 05- Sorted List (array based) Solution

In today’s lab we will design and implement the List ADT where the items in the list are sorted.
sortedtype.h

#ifndef SORTEDTYPE_H_INCLUDED
#define SORTEDTYPE_H_INCLUDED

const int MAX_ITEMS = 5; template <class ItemType> class SortedType
{ public :
SortedType(); void MakeEmpty(); bool IsFull(); int LengthIs();
void InsertItem(ItemType); void DeleteItem(ItemType); void RetrieveItem(ItemType&, bool&);
void ResetList();
void GetNextItem(ItemType&); private:
int length;
ItemType info[MAX_ITEMS]; int currentPos;
};
#endif // SORTEDTYPE_H_INCLUDED
sortedtype.cpp

#include "sortedtype.h" template <class ItemType>
SortedType<ItemType>::SortedType()
{ length = 0; currentPos = - 1;
} template <class ItemType> void SortedType<ItemType>::MakeEmpty()
{ length = 0;
} template <class ItemType>
bool SortedType<ItemType>::IsFull()
{ return (length == MAX_ITEMS);
} template <class ItemType> int SortedType<ItemType>::LengthIs()
{ return length;
} template <class ItemType> void SortedType<ItemType>::ResetList()
{ currentPos = - 1;
} template <class ItemType>
void SortedType<ItemType>::GetNextItem(ItemType& item) { currentPos++;
item = info [currentPos];
} template <class ItemType>
void SortedType<ItemType>::InsertItem(ItemType item)
{
int location = 0;
bool moreToSearch = (location < length);

while (moreToSearch)
{
if(item > info[location])
{
location++;
moreToSearch = (location < length);
}
else if(item < info[location]) moreToSearch = false;
}
for (int index = length; index > location; index--)
info[index] = info[index - 1]; info[location] = item; length++;
}
template <class ItemType>
void SortedType<ItemType>::DeleteItem(ItemType item)
{
int location = 0;

while (item != info[location]) location++;
for (int index = location + 1; index < length; index++)
info[index - 1] = info[index]; length--;
}
template <class ItemType>
void SortedType<ItemType>::RetrieveItem(ItemType& item, bool& found)
{
int midPoint, first = 0, last = length - 1; bool moreToSearch = (first <= last); found = false;
while (moreToSearch && !found)
{
midPoint = (first + last) / 2; if(item < info[midPoint])
{
last = midPoint - 1;
moreToSearch = (first <= last);
}
else if(item > info[midPoint])
{
first = midPoint + 1;
moreToSearch = (first <= last);
} else {
found = true;
item = info[midPoint];
}
}
}
Generate the driver file (main.cpp) where you perform the following tasks. Note that you cannot make any change to the header file or the source file.

Operation to Be Tested and Description of Action Input Values Expected Output
• Create a list of integers
• Print length of the list 0
• Insert five items 5 7 4 2 1
• Print the list 1 2 4 5 7
• Retrieve 6 and print whether found Item is not found
• Retrieve 5 and print whether found Item is found
• Print if the list is full or not List is full
• Delete 1
• Print the list 2 4 5 7
• Print if the list is full or not List is not full
• Write a class timeStamp that represents a time of the day. It must have variables to store the number of seconds, minutes and hours passed. It also must have a function to print all the values. You will also need to overload a few operators.
• Create a list of objects of class timeStamp.
• Insert 5 time values in the format ssmmhh 15 34 23
13 13 02
43 45 12
25 36 17
52 02 20
• Delete the timestamp 25 36 17
• Print the list 15:34:23
13:13:02
43:45:12
52:02:20
