Not telling us about variables you're using in practice

[KaraNomad]

specifically during the array section with the for loops the answer keeps requiring a variable the non of the prior lessons tell you that you're using
like with the drawing the rectangles with a for loop it never states anywhere that you're using a variable named "size" so it makes it impossible to figure out what the correct answer is supposed to be without just looking at the full solution
this is done multiple times in the array part of the course so please fix this
