CMU CS Academy Unit 2 Checkpoint

Since we did not set its fill using the fill argument, we cannot modify its fill later.

• True

• False

We can define a function without any parameters.

• True

• False

Using the variable name orangeStar1 for a purple rectangle will cause an error.

• True

• False

We need to call onMousePress in our code before it will react to mouse presses.

• True

• False

What happens when the mouse is pressed once while running the following code?

• The opacity of the oval decreases.

• The oval moves to the left.

• There is an error on the last line of code.

• There is an error because the onMousePress parameters have the wrong names.

Which of the following is drawn when the mouse is released while running the following code?

• A blue rectangle covering part of a green rectangle.

• Two non-touching rectangles.

• A green rectangle.

• Two overlapping rectangles of different colors.

Select the answer that correctly calls these functions to draw the image. Hint: You can use the drawing order of the shapes to help you narrow down the answer.

• drawStar(275, 150) drawCircles(125) drawCircles(275) drawStar(125, 250)

• drawCircles(125) drawCircles(275)

  drawStar(275, 150) drawStar(125, 250)

• drawStar() drawCircles()

• drawStar(275, 150) drawCircles(125) drawStar(125, 250)

We can set any general shape property (except align) for a shape if we have a global variable storing the shape.

• True

• False

Running this code will draw a rectangle with a fill of None.

• True
