Here's how it looks with a while loop. Note the difference regarding where you increment x and y.

int x = 0;
while (x < width) {
  int y = 0;
  while (y < height) {
    noStroke();
    fill(random(255));
    rect(x,y,10,10);
    y += 10;
  }
  x += 10;
}

I was able to complete first half of ex. 6-8. I cannot figure out how to re-create the same pattern using a “while” loop. This is one of the many attempts I’ve made:

size(200,200);
background(255);

int r = 0;
int g = 0;
int b = 0;

int x = 0;
int y = 0;

while (x while(y rect(x,y,10,10);
x+=10;
y+=10;
}
println("x = "+x);
println("y = "+y);
}

// r = int(random(255));
// g = int(random(255));
// b = int(random(255));
// fill(r,g,b);

Thanks!

You just need to use 3 arguments to fill(), i.e.

fill(random(255),random(255),random(255));

What should I do if i want to use random r,g,b to color them? I was told fill(random(r,g,b)); is not applicable..
