for loop in a for loop


Recommended Posts

So you are trying to do it in Java then.


I can't help because I don't write Java, so I've moved it to the Java forum. I can tell you there is no reason you need more than one loop. Here's the PHP code:


for($i=0; $i<=9; $i++){
        $string = "$i";
   	$string = $i.$string;
   echo $string.'<br>';


PS: If this is homework, you need to learn to do it yourself. See the rules.

I think maybe the point was to get you to look at how to control the flow of nested loops ...


public class Answer {
   public static void main(String argv[]) {
       for ( int start = 0; start <= 9; start++ ){
           System.out.printf("%d", start);
           for ( int inner = start-1; inner>=0; inner-- ){
               System.out.printf("%d", inner);


Jessica is right, you should try to do this for yourself, at the very least make sure you understand the answer, look for ways to improve it, perhaps find another way using a different control structure ...


Have fun :)
