Question 25/68
Consider the following code:
```
<?php
function modvalue()
{
       $a=20;
       $b=4;
       $c=$a%$b;
       print($c);
} 
modvalue();
?>
```
What will be the value of the variable c?
4

0

20

5
Explanation:
The value of the variable c will be 0. The modulus (%) operator is used to find out the remainder after a division has been completed. This can be used with integers and floating point numbers.

The following example will demonstrate the use of the modulus operator:

<?php
$a=10;
$b=4;
$c= $a%$b;
print($c);
?>

In the above program, the value of variable c will be 2.
