DO_WHILE Statements

Chapter 6 #119 - Martha's CIS 52

ASSIGNMENT/EXPLANATION

The do...while statement looks like an upside-down while statement. The effective difference is that the do...while statement's code block is executed BEFORE the truth test, and not after it. NOTICE: the test condition (the while portion) must end with a semi-colon.

Example 119b sets the counter variable at 300, so this time the code prints a line for each number between 300 and 399 (which is less than 400). Compare this to Example 119a.

Exercise

CODE

<?php 
$num = 300;
do {		  
    echo "The number is: ".$num."<br />";		
    $num++;	
   } while (($num > 200) && ($num < 400));
?>
