Create a partially-full array that can hold up to 1000 (x,y) coordinate pairs. In order to do this, you will have to create 2 parallel arrays (one for X coordinates, and one for Y coordinates), as well as a variable to hold the current number of points stored in the arrays. These must be global state variables. Use a canvas size of 500x500. Implement the void mouseClicked() function which is automatically called every time that the mouse is clicked in the canvas. When this happens, add the location (mouseX, mouseY) to the stored list of coordinates. The void draw() function should clear the canvas, and then draw circles with their centres at all of the stored (x,y) points that have been clicked. The circles should have a diameter of 20 pixels, and should be drawn in random colours that change every frame, so that they apnear to “flicker"

Topic: Use of Patial- Full Arrays

A partially-full array of (x,y) points
1. Create a partially-full array that can hold up to 1000 (x,y) coordinate pairs. In order to do
this, you will have to create 2 parallel arrays (one for X coordinates, and one for Y
coordinates), as well as a variable to hold the current number of points stored in the arrays.
These must be global state variables.
2. Use a canvas size of 500x500.
3. Implement the void mouseClicked() function which is automatically called every time
that the mouse is clicked in the canvas. When this happens, add the location
(mouseX, mouseY) to the stored list of coordinates.
4. The void draw() function should clear the canvas, and then draw circles with their
centres at all of the stored (x,y) points that have been clicked. The circles should have a
diameter of 20 pixels, and should be drawn in random colours that change every frame, so
that they appear to "flicker".
