Banana Cake
Instructions
- Assume an action set of {add <ingredient>, stir, bake, cool}. Draw a flowchart, using the paradigm discussed in class, to show the process of baking a banana cake. Use Google to find a typical list of ingredients.
- Represent the flowchart from problem 1 as pseudocode.

Walking
Instructions
-
Assume an action set of {walk <value> steps, turn to <value> degrees}. Draw a flowchart showing a shady path and a sunny path to get from the west doors of the Engineering Building to the south-east doors of the TSC. Pick a meaningful “if” condition to select one of the two paths. Use real-world data in your design.
-
Represent the flowchart from problem 3 as pseudocode.
%% Assuming a step distance of 2.5 feet.
Shady path:
- Turn to 270 degrees
- Walk 112 steps
- Turn to 225 degrees
- Walk 124 steps
- Turn to 270 degrees
- Walk 361 steps
- Turn to 0 degrees
- Walk 176 steps
- Turn to 270 degrees
- Walk 62 steps
Sunny path:
- Turn to 270 degrees
- Walk 73 steps
- Turn to 0 degrees
- Walk 94 steps
- Turn to 275 degrees
- Walk 467 steps
- Turn to 180 degrees
- Walk 86 steps
- Turn to 270 degrees
- Walk 80 steps

4 Way Intersection
Instructions
-
Develop a flowchart that describes the behavior of a set of traffic lights that control a 4-way intersection. Assume the light can either be red or green. Define an appropriate action set that accounts for the time the light has been in the current state.
-
Represent the flowchart from problem 5 as pseudocode.
Action Set
| Action name | Description |
|---|---|
| Set [north, east, south, west] light to [red, green] | Set the specified light to either red or green |
| Toggle lights | Change the color of all 4 lights to the color they were not |
| Wait [number of seconds] seconds | Pause for [number of seconds] seconds before continuing to the next instruction |
