Thread 2, Day 5 - Thursday, January 19, 2023

Agenda

1. Lesson: Interactive Applications Using Sliders
   • Input-Process-Output
     • Writing applications that accept input, process it, and display output.
     • We will write an app that calculates the area of a square or rectangle.
     • Here are the instructions from class, in order... each video is quite short:
       • 1 - Creating the Project
       • 2 - Organizing the Project with a New View
       • 3 - Create a Static Layout.
       • 4 - Add Properties to Begin Making an Interactive Layout
       • 5 - Add Sliders To Allow for User Input
       • 6 - Using the Group Structure to Work Around the Ten View Limit
     • Now, please take the app you have written, and extend it to calculate perimeter as well.
2. Exercise: Temperature Converter
   • Write an application (from scratch, in a new project) that converts a temperature in Celsius to its equivalent in Fahrenheit.
     • Optionally:
       • Also write a page that calculates the reverse: from Fahrenheit to Celsius.
       • Add navigation to the app so that the user can move between these screens.

To-do items

Before our next class...

• Extend your Area and Perimeter app to calculate and display the perimeter of a given rectangle.
• As described above, write a Temperature Converter app.
• Share updates on Spaces.
