This program will be the template you will use to practice writing code using arrays. All you will need is to write the function, and you will assume an existing array. This program has an existing example function called findAverage.

<title>Program with Arrays Template</title>
<script type = "text/javascript">
<!--
var a = new Array( 100 ); // create an Array
var count = 0;
var out = "";
function buttonPressed()
{
var searchKey = searchForm.inputVal.value;
if ( searchKey == "" )
findAverage();
else
{
a[count] = parseInt(searchKey);
count++;
searchForm.inputVal.value = "";
searchForm.inputVal.focus();
}
}
function findAverage( )
{
var sum = 0;
for ( var n = 0; n < count; ++n )
sum = sum + a[n];
searchForm.result.value = sum/count
for ( var x=0; x<count; x++)
out = out + a[x] + ", ";
searchForm.arrayout.value = out;
}
