//  Copy of example problem in prelab section (step 2) that demonstrates
//  using a list to read in a set of numbers and then traverse the list
//  calculating the sum of the numbers in the list
//
//--------------------------------------------------------------------

// For this example, set DataType to "int" in listarr.h,

#include <iostream>
#include "listarr.h"   // Include the class declaration file

using namespace std;

void main ()
{
    List samples(100);        // Set of samples
    int newSample,            // Input sample
        total = 0;            // Sum of the input samples

    // Read in a set of samples from the keyboard.

    cout << "Enter list of samples (end with eof) : ";
    while ( cin >> newSample )
        samples.insert(newSample);

    // Sum the samples and output the result.

    if ( !samples.isEmpty() )            // Verify that list has data
    {
       samples.gotoBeginning();          // Go to beginning of list
       do
         total += samples.getCursor();   // Add element to running sum
       while ( samples.gotoNext() );     // Go to next element (if any)
    }

    cout << "Sum is " << total << endl;
