Example of documenting a program

Simpsons program

Flowchart (Homer moves forward, greets Bart, Bart greets Homer)

Linear program (Simpsons)

Flowchart (Same as previous version except Homer moves and greets at the same time)

Linear program, simultaneous execution (Simpsons v2)

Displaying the contents of variables (using 'say' or 'think')

Variables v1

Displaying mixed output (mixing strings and numerical values) when displaying the contents of variables

Variables v2

Branching (if-else). Program asks for the user's name and it reacts differently for one particular user.

If-Else V1

Branching (if-else). Identical to the previous program except that there is an additional instruction after the branch that's always executed.

If-Else V2

Branching and generating random numbers

Dice simulation

Branching (logical OR): a program to determine if a candidate should be hired

Hiring program (Alice program)

Hiring program (Flowchart)

Branching (logical AND): a program to determine if an existing employee should be fired

Firing program (Alice program)

Hiring program (Flowchart)

Multiple successive branches (camel's appearance changes depending upon the answer to the questions, the result of both questions are independent)

Multiple branches

Nested branches (camel's appearance changes again but now the answer to one question determines if the other question is asked)

Nested branches

Simple loops (an evil ninja jumps up and down 5 times) uses the 'loop' instruction

Loop (Alice program)

Loop (Simple flowchart)     Loop (complex flowchart)

More advanced loop, the number of jumps is determined by user input, uses the 'while' instruction

While loop (Alice program)

While loop (Flowchart)

While loop (Flowchart: page 1: page 2: page 3)
