Draw a capital C with a black pen that is 2 pixels thick. The letter is 65 pixels wide and 80 pixels high. Use a half-circle for its rounded left side. Leave the right side open.

The turtle starts in the center of the canvas, facing east.

1. Lift the pen and move to (0, 40). Lower the pen and draw a line to (25, 40).
2. Lift the pen and return to (0, 40).
3. Face west. Draw a half-circle with radius 40. It curves around the left side and ends at (0, -40).
4. Draw a line to (25, -40).
