Learning Outcome

At the end of this lesson, you will be able to:

• make Pseudo-code
• format a string to look like money

Review

• review using constants
• review flow-charts

Lesson

• go over "Pseudo-code", Chapter 2
  • Computer Based Problem Solving
• go over 6 Steps to Solve Computer Problem
  • this is now your model for creating a program
• in Swift, this is how you format a variable to look like money
  • String(format: "The pizza costs: $%.02f", cost)
  • print('The cost is: ' + '${:,.2f}'.format(cost)) -> (this is for Python)

Activity

• work through "pizza" program to create:
  • top-down design
  • flow-chart
  • pseudo-code

Daily Assignment

• create the top-down, flow-chart and pseudo-code for:
  • the cost of making a pizza is:
    • labour cost is $0.75 / pizza, regardless of the size
    • rent on the shop is $1.00 / pizza, regardless of the size
    • materials are $0.50 / diameter inch of pizza
  • create a program that calculates the total cost (don't forget HST) for a given diameter pizza.
• once the design document is done, show me
  • then write the program
• it should look like this

Extra

• create the above program in a second language
