Question

$y=1990;
$r=0.035;
$ny=$y++;
$count=1;

$np=$p+($p*$r);
$y=$y+1 /*calculate the rate of growth of population in a year*/;

$count++;}
echo "<br/><br/><h2>the populatuon will be<Mem>$np</em>in year <u>$y</u></h2>"/*print the year that the population reached 50000000 and stop*/ ;

WHY DOES'NT IT STOP

Answer 1

You haven't changed $p inside the loop if I'm seeing right. So $p will remain less than 50000000 forever and loop will run 🏃 forever :)

Answer 2

The same, $p not appear into while and always have the same initial value

Answer 3

what is $p and what is $np? if you use $p for the while then you must to write something to increase to arrive sometime to break condition

Answer 4

Maybe you must to fix
$np=$p+($p*$r)
per
$p=$p+($p*$r)

Answer 5

so what should I change
