problem in outstream

[elsa87]

hi everyone..
i have a small problem with the below code..
when i execute the program, the output file doesnt print me the unsortedList.ReturnLastItem().Print();
it gives me the following output:
the last item in the unsortedList is
how can i make it print me the last item?
here is the code:

#include <iostream>
using std::cin;
using std::cout;
using std::endl;
#include <cstdlib> 
#include"ItemType.h"
#include <fstream>
using std::ifstream;
using std::ofstream;
class UnsortedListType 
{
public:
UnsortedListType();
int LengthIs() const;
void Push(ItemType item);
void ResetList();
void GetNextItem(ItemType& item);
int GreaterThanItem(ItemType givenItem);
ItemType  ReturnLastItem();

private:
int length;
ItemType info[MAX_ITEMS];
int currentPosition;
};

UnsortedListType::UnsortedListType() 
{
	length=0;
}


int UnsortedListType::LengthIs() const 
{
	return length;
}
void UnsortedListType::Push(ItemType item)
{
	info[length]= item;
	length++;
}
void UnsortedListType::ResetList()
{
	currentPosition = -1;
}
void UnsortedListType::GetNextItem(ItemType& item)
{
	currentPosition++;
	item = info[currentPosition];
}
void PrintUnsortedList(UnsortedListType unsortedList)
{
	int length;
	ItemType item;
	unsortedList.ResetList();
	length = unsortedList.LengthIs();
	for( int i = 1; i <= length; i++)
	{
		unsortedList.GetNextItem(item);
		item.Print();
	}
	cout<<endl;
}
int UnsortedListType::GreaterThanItem(ItemType givenItem)
{
    int counter=0;
    int location=0;
    while (location<length)
    {
if (givenItem.ComparedTo(info[location])==LESS)
     	   {
        		counter++;
		location++;		
      	  }
else
	location++;        
    } return counter;
}
ItemType UnsortedListType::ReturnLastItem()
{
return (info[length-1]);
}
int main()
{
	ItemType item;
	UnsortedListType unsortedList;
	int data;

	ifstream instream; 
	ofstream outstream;

	instream.open("input.txt");
	if(instream.fail()){
    	cout<<"Error opening file\n";
exit(1);
}
	
	instream>> data;
	item.Initialize(data);
	unsortedList.Push(item);
	while ( !instream.eof() )
	{	
		instream>> data;	
		item.Initialize(data);
		unsortedList.Push(item);
	}
	instream.close();

	PrintUnsortedList(unsortedList);
	cout<<"the last item in the unsortedList is ";
	unsortedList.ReturnLastItem().Print();
	cout<<endl;
	cout<<endl;
	cout<<"insert a number "<<endl;
	cin>>data;
	item.Initialize(data);
	cout<<"the number of elements greater than the numbered you entered is "<<unsortedList.GreaterThanItem(item)<<endl;
	cout<< endl; 

	outstream.open("output.txt");
	if (!outstream) 
		return 0; 
	outstream<<"the last item in the unsortedList is ";
	unsortedList.ReturnLastItem().Print();
	outstream<<endl;
	outstream<<"the number of elements greater than the numbered you entered is "<<unsortedList.GreaterThanItem(item)<<endl;

outstream.close();
	return 0;
}

post ItemType.h code.

[elsa87]

here is the ItemType.h code:

const int MAX = 20;
enum RelationType {LESS, GREATER, EQUAL};
class ItemType {
public:
ItemType();
RelationType ComparedTo(ItemType) const;
void Print() const;
void Initialize(int number);
private:
int value;
};
ItemType::ItemType()
{
value=0;
}
RelationType ItemType::ComparedTo(ItemType otherItem) const
{
if (value < otherItem.value)
return LESS;
else if (value > otherItem.value)
return GREATER;
else return EQUAL;
}
void ItemType::Initialize(int number)
{
value = number;
}
void ItemType::Print() const
{
cout<<value<<" ";
}

Is it succesfully compile?..

[elsa87]

yes it compiles without errors and runs also
but the problem is that is the output file, the last item in the list is not printed there..
how can i print this?
the problem is here

outstream<<"the last item in the unsortedList is ";
	unsortedList.ReturnLastItem().Print();
	outstream<<endl;

[cikara21]

outstream<<'get last item here';

[elsa87]

lol
that's not what i meant..
what u gave me is already there but the value of that last item can't be printed..i just need to understand how to print the value

[cikara21]

I mean..Add this on ItemType.h

int ItemType::getval()
{return value;}

then

outstream<<unsortedList.ReturnLastItem().getval();

[elsa87]

Thanks alot cikara21..
glad it's finally solved

[cikara21]

No problem
