Task 1: Design the Flowchart

First you will design the flowchart for your algorithm. The aim is your algorithm is to:

  • Ask the user how many adult tickets are needed,
  • Ask the user how many child tickets are needed,
  • Calculate the total cost of this order,
  • Decide if this order qualifies for a 5% discount and if so, calculate the new total cost of the order,
  • Output the total cost of the order.

Task 2: Python Code

Once your flowchart is complete, implement your algorithm using Python code.

Task 3: Test Plan

Test # Type of Test Input Values Expected Output Actual Output
#1 Valid Adults: 2
Children: 1
Total Cost: £41
#2 Valid Adults: 1
Children: 0
Total Cost: £15
#3 Valid Adults: 2
Children: 3
Total Cost: £59.85
#4 Valid Adults: 5
Children: 12
Total Cost: £196.65
#5 Valid Extreme Adults: 0
Children: 0
Total Cost: £0
#6 Erroneous Adults: abc
Children: xyz
Error Message

Task 4: Adding extra validation routines

Tweak your code to add some validation routines when capturing user inputs. For instance, you want to make sure that the user only enters a positive integer value when asked for the number of tickets required.

You might find this blog post useful to ensure the user provides an integer value when asked to do so.

Adding validation routines when capturing user inputs is always a good approach to improve your programs and make them more robust.

You can investigate other forms of validation routines on this page.
