Transcript

Consider the following program: 
a = 12.1
c = 8.6
a = 1.5
b = 0.6
if a > 6:
    a = b
else:
    a = c

c = b
Walk through the program above step by step using an environment diagram that you draw yourself. Then create an environment diagram using the interface below that shows the state of program memory once all of the instructions above have run:
×

1. Drag objects into the field to construct a diagram.

2. Use dots to create lines for variable bindings and pointers.

3. Don’t like a line? Redraw from the source dot to remove.

4. Don’t like an object? Move to trash.

5. Don't like arrow placement? Try moving objects around to redraw.

6. Add annotations if you'd like. They don't affect correctness.

×
Are you sure you want to reset the diagram back to the starter state?
