Help with class array output

[seanster]

Here's what i got

main file

#include<iostream>
#include "elements.h"
using namespace std;
int main( )
{
	int StrgAmt;
	int number;
	Data bo[10];

	cout<<"How many elements do you want? : "<<endl;
	cin>>StrgAmt;

	for(int i=0;i<StrgAmt;i++){
		cout<<"Fill in the array: "<<endl;
		cin>>number;
		
	}
	for(int j=0;j<StrgAmt;j++){
		bo[j].setItem(number,StrgAmt);
		cout<<bo[j].getItem();
	}

	return 0;
}

elements.h

#ifndef _Data_BOX
#define _Data_BOX

// Set the type of data stored in the box
typedef double ItemType;

// Declaration for the class PlainBox
class Data
{
  private:
// Data field
  static const int Default_Size=10;
  ItemType vStore[Default_Size];
  int capacity; 
  int num_used;
  public:
// Default constructor
	Data ();
	bool isFull();
	bool isEmpty();
	int arrayCapacity();
	int numUsed(const ItemType& Entry);
	Data (const ItemType&  Entry);
	void setItem (const ItemType& Entry, int num_used);
	ItemType getItem () const;
	int ADD(const ItemType& Entry);
	int PosOfElem(const ItemType& Entry);

};  
#endif  

elements.cpp

#include "elements.h"

Data::Data ()
{
	capacity=10;
	  num_used=0;
}   // end default constructor

Data::Data (const ItemType& Entry){ }   // end constructor

bool Data::isFull(){return 0;}
bool Data::isEmpty(){return num_used==0;}
int Data::arrayCapacity(){return capacity;}
int Data::numUsed(const ItemType& Entry){return 0;}
void Data::setItem (const ItemType& Entry, int num_used){
	vStore[num_used]=Entry;
}  

ItemType Data::getItem() const{
  return vStore[num_used];
}  
int Data::ADD(const ItemType& Entry){
	bool ExtraRoom= (num_used < capacity);
	if (ExtraRoom){
		vStore[num_used] = Entry;
		num_used++;
	}
	return ExtraRoom;
}
int Data::PosOfElem(const ItemType& Entry){return 0;}

I keep getting numbers in exponential form in the output when i try to print it all out. How to fix it? thanks for taking time out to help.

use setprecision() function

It still doesnt work, what im trying to do is add elements to an array using the set function, then printing them out using the get function but i keep getting the same exponent number every time i print out the array

How did you used the setprecision()?
