    Default for loop output

    hi guys we are learning loops this week at uni and a tute was to get the output
    1 2 3.... 10
    11 12 13.... 20
    ........
    91 92 93...... 100

    i got this working but not sure if i did it right... Did i miss something here or is this how it would be done?

    Java Code:
    int i;
    int j;
    
    for( i=1; i <= 10; ){
       for( j=1; j <= 10; j++){
          System.out.print(i + " ");
           i++
       }
       System.out.println();
    }

    might be typos... My net is down so typing this on mobile

    thanks guys

    The code is fine (ignoring a few little typos).

    kind regards,

    Ahem, Jos!

    The outer loop counter is being incremented inside the inner loop (ignoring the missing semicolon) -- and take a closer look at what's being printed .

    It must've been 'wishful reading' on my part, sorry about that. I must've mentally constructed the correct code given the pieces that were shown, how silly of me ...

    kind regards,

    Hint: Only one loop is required, and the modulus operator will come in handy.
