Im stumped, need help. (Read 541 times)

Im stumped, need help.
May 2^nd, 2006, 9:18pm

size (300,300);
smooth ();

for (int a = 0; a < 300; a= a+10){
for (int b= 0; b < 300; b = b+10){

line (a,0,b,300);
}}

I can't understand why this doesn't work.
I just wanted to draw vertical lines across
the screen but it becomes this crazy weird
image.

I slept on it and still am completely lost.
Sorry for being completely clueless, I'm
beginning (and enjoying) the learning process.

I prefer yours to be honest, but here you go!

Code:



size (300,300);
smooth ();
 
for (int a = 0; a < 300; a= a+10) {
   
  line (a,0,a,300);
}

p.s

Your code will have drawn 30 * 30 lines, because the outer loop will have only been re-tested, once the inner had been satisified. sorry, bit of a crap explanation.
There'll be plenty on the web and probably this forum covering nested conditionals
