Code Academy help…

    Hi guys and girls

    I am just working my way through a Javascript section on Code Academy and I’m really liking it up to now, however I’m stuck on this question;

    **The President has notified you that he only wants you to square the ODD numbers between 100 and 150.**

    **Add an if…else statement to your for loop block that looks at each number. If it is odd, print the square of the number. Otherwise, just print the number.**

    I had this but I think I’m way off;

    for (var i = 100; i < = 150; i++) {
    var square = i % i;

    if (square) {
    print (square);
    }
    else {
    print (square)
    }
    }

    I think you want to do

    if(i % 2) {
    print i*i;
    }

    It checks to see if there’s a remainder from i divided by 2. If there is then i is odd. If it is odd then square it.

    @tbwiii

    Thanks so much :) I had to amend it a tiny bit but you were right;

    for (var i = 100; i < = 150; i++) {

    if (i % 2) {
    print (i * i);
    }
    else {
    print (i);
    }

    } //End of for statement

    Sorry! I was on my phone at the time or I would have typed the whole solution out :)

    It’s okay :) you gave me what I needed really. Helped me get more used to the syntax adding the brackets etc. Really liking this JavaScript atm
