Re^3: Repeat question (redo)

You would put one of the constructs suggested by haukex or LanX inside the while from your original code, around your if/else block.

(Also, rather than having that if/else block, and repeating two almost-identical pieces of code: after generating the two random numbers, I would suggest using this to swap them, so the first is always bigger than the second:

if($random_integer1 < $random_integer2) 
{ 
    my $tmp = $random_integer2; 
    $random_integer2 = $random_integer1; 
    $random_integer1 = $tmp;
}

That way, you only need one piece of code for asking and checking the answer, rather than two nearly-identical pieces. There are more perlish ways of doing the swap, but I chose to make it easy for you to understand.)

This is perfectly OK, but the temporary variable is not really needed and this can be simplified as follows: `($random_integer1, $random_integer2) = ($random_integer2, $random_inte +ger1) if $random_integer1 < $random_integer2;` [download]	[reply] [d/l]

that was exactly one the "more perlish ways" I was referencing. I would have done it that way for myself, but I thought the explicit swap was more concrete for the OP to understand what was going on.	[reply]

Yeah, I guess I missed the last sentence of your previous post when I first read it. I might not have reacted if I had seen it. Still, I think it was useful to show this other way of swapping values without using a temporary variable.	[reply]
