A checkerboard, or chessboard. is a flat surface with a checkered tile pattern on it. The tiles alternate between light and dark colours (typically white and black). Figure 1: A 4x4 black and white checkerboard Your task is to draw a 4x4 black and white checkerboard in Processing that fills the entire space of a 200x200 pixel canvas. Have the top-left most tile coloured white like in the figure. Make sure to write helpful comments throughout your code. Especially with longer programs, it can be- come difficult to know what your code is doing from a glance. Comments make your program easier to read and easier to find errors, so get into a good habit of commenting your code! Don't overdo it though as too many comments can be just as much a hinderance as too few. Hint: Depending on the approach you take, you may find the Processing command oStroke () useful Calling this before you draw any shapes removes the black outline drawn around them.
