Overview

Purpose: Learn how create a structure chart to document the methods within a program.
Task: Create a structure chart for your program from PP Task 7.1 .
Learning Outcomes:
Time: Aim to complete this task before the start of Week 8.
Resources: • Introductory Programming Notes: 0 13 Functional Decomposition
Note: This task should be attempted after you are satisfied with your solution to PP Task 7.1 . You do not need to wait until you have had 7.1 PP formally assessed.
Submission Details
Upload the following to the MyLO submission folder for this task: ‘ An image of your structure chart (photo or scan)
Assessment Criteria
A Completed submission will:
Not show methods declared outside your source code
Have arrows indicating calls between methods
Have data shown next to the arrows indicating the direction the data is travelling
Instructions
Create a structure chart for the program you created in PP Task 7.1 .
Structure charts provide an effective way of communicating the methods within a program. To create a structure chart you would do the following (an example is shown below, and more details are given in Part 13 of the Introductory Program Notes on MyLO):
1. Draw a box for the program’s main() method at the top of the page o Write the text main within the box; this now represents the main method
2. Draw a box for each of the methods that main() calls. Position these below the box for main so that you can easily draw arrows from the bottom of main to the methods it calls o Write the name of each method within the box o Draw an arrow from main to the method’s box o Next to the line draw smaller arrows to indicate the data that will be passed to, or returned from, the method

This kind of diagram can be used to either communicate the structure of an existing program or as a design tool to help you think about how your program will be organised.
Note: No need to include nextlnt() or next() for example, as those are in the Scanner class. Do include readReading (readExpense, etc.) as it is in the program’s code.
