Why doesnt this work?
Posted: Mon Jun 16, 2008 8:27 pm
I was trying (long explanation as to why) to find out all the possible combinations to get below 9.5 but above 8.5 as the final grade of a course that consists on three tests, two quizes and extra points if you get 10 or more on each test (0.5, 0.5 and 1 extra point respectively).... I tried this very simple algorithm but for odd reason the highest grade its 18, not 20..... it appears to not be adding the extra 0.5s and 1... any help appreciated.
Code: Select all
<?php
for($i=0;$i<=20;$i++)
{
$definitiva=0;
for ($j=0;$j<=20;$j++)
{
$definitiva=0;
for ($k=0;$k<=20;$k++)
{
$definitiva=0;
for ($l=0;$l<=20;$l++)
{
$definitiva=0;
for ($m=0;$m<=20;$m++)
{
$definitiva=0;
$definitiva=($i/4)+($j/4)+($k*3/10)+($l/20)+($m/20);
if($i>=10)
{
$definitva+=0.5;
}
if($j>=10)
{
$definitva+=0.5;
}
if($k>=10)
{
$definitva++;
}
if($definitiva>17)//($definitiva>=8.5)&&($definitiva<9.5))
{
echo "Has podido sacar " . $i . " , " . $j. " , " . $k . " en los parciales y ". $l ." , " . $m . " en los talleres y te daba ".$definitiva ."<br>";
}
}
}
}
}
}
?>
