[ijustdidit2011]

Im trying to get the average of these scores for school could some one tell me what im doing wrong?

 

Thanks!

 

 

<?php

//mainline

 

$scores=array("6.7","8.1","5.8","7.0","6.6","6.0","7.6","6.1","7.2","7.0");

$judges=array("America","Germany","France","China","Japan","Russia","Chek Republic","Trinidad","Cuba","Jamaica");

$average=0;

 

 

doCalc($scores, $average);

//end mainline

 

    function doCalc($scores, $average)

{

  $scores[$average] = $scores[$average] / 10;

  $average = $scores[$average];

}

 

 

 

 

print("The scores are:  ");

for($i=0; $i<10; $i++)

{

print("\n\n{$judges[$i]}");

print("\n{$scores[$i]}");

 

}

print("\n\nThe Average score is $average");

?>

You're numbers are strings in the array. The first thing I might try is:

 

$scores = array(6.7, 8.1, 5.8, 7.0, 6.6, 6.0, 7.6, 6.1, 7.2, 7.0);

You are not returning any values in your function, so the $scores and $average variables are terminated at the closing } of your function. To prevent this you could pass the parameters like this:

 

function doCalc( &$scores, &$average )

 

This is called passing variables by reference. It means that everything you do to those variables in your function, will stay that way, even when the function is closed.

Try this mate.

 

<?php
//mainline

   $scores=array(6.7,8.1,5.8,7.0,6.6,6.0,7.6,6.1,7.2,7.0);
   $judges=array("America","Germany","France","China","Japan","Russia","Chek Republic","Trinidad","Cuba","Jamaica");
   $average=0;   
   
   
   $average=doCalc($scores, $average);
//end mainline
   
    function doCalc($scores, $average)
   {
      $total=0;
      foreach($scores as $score) {
        $total=$total + $score;
      }
      $result=($total / 10);
      return $average;
   }

   


print("The scores are:  ");
for($i=0; $i<10; $i++)
   {   
   print("\n\n{$judges[$i]}");
   print("\n{$scores[$i]}");
   
   }
   print("\n\nThe Average score is $average");
?>

 

Set it to loop through the array and add it all up and then return the average.
