2. No Yes START Do you live in Scotland? Take umbrella See last Flowchart
END

3. What is this controlling?
a car park for 10 cars

4. Learning Intention
I will learn about the iterative software development process with a focus on the Design stage.

5. Analysis
Design
Implementation
Testing
Documentation
Evaluation

6. Design Notations 3 design notations: Structure Diagram Flow charts
Pseudocode
Focus today on Flow Charts

7. DESIGN - Flow Chart
Uses a variety of symbols with text to represent the order of events required to solve a problem.
Symbols in the flowchart can be equated to programming constructs such as:
assignment (=)
selection (IF)
Repetition (Loops)

8. Terminal: “start” and end”
Flow Chart
Input / Output
Flow line
Pre-defined process
Decision
Terminal: “start” and end”
On page connector
Process
Initialisation: declare variables etc

9. e.g. old enough to drive? Start Take in age Display “old enough”
End
YES
Display “too young”

10. Create your own flow charts for the following problem:
A program which asks the user to enter their password then checks if they are allowed to login or not.

12. Worksheet
In your jotter, complete the 2 Flow Chart questions from the Graphical Design Notations worksheet.

13. Structure Diagrams and Flow Charts
Advantages
structure is very clear
flow of program is very clear
Disadvantages
adding more details means diagrams become very complicated

14. Success Criteria
I can use structure diagrams and flow charts to design a solution to a problem.
