1. [2 pts] Consider the following code that draws many lines. There are 13 calls to the line function: observe the parameters that stay the same and the ones that change.

Write a program called manyLinesLoop.pde that produces the same output using a for loop. Only 3 statements are needed in your program.

2. [4 pts] Write a program manyLinesGrid.pde that uses a for loop to create an output similar to the image below.

• The application window is 200 pixels wide and 200 pixels high.
• The lines are separated by 10 pixels in each direction: horizontal and vertical.
• The padding (space around the grid) is 20 pixels on all the sides.

3. [2 pts] Write a program ellipseLoop.pde that creates an output similar to the image below.

• The application window is 260 X 260 pixels.
• The background is white.
• The circles are centered in the window.
• The smaller circle is 40 by 40.
• The circles are separated by 20 pixels.

4. [2 pts] Consider the following code that creates a rainbow gradient as shown below.

Write a program ellipseRainbow.pde that creates an output similar to the image below.

• The application window is 260 X 260 pixels.
• The background is white.
• The rainbow is centered in the window.
• Its radius is 255 pixels.

Bonus Write a program to create a gradient similar to the one shown in the following image.

Once you have successfully made a monochrome gradient change the gradient to color (red or blue or green for example).
