Worked Solution & Example Answer:The ice cream kiosk has a set of freezers for storing ice cream - Edexcel - GCSE Computer Science - Question 9 - 2019 - Paper 1
Step 1
Determine Freezer Tolerance
Answer
To start, we define the perfect temperature for ice cream storage as -18°C. Given the permissible tolerance of ±1°C, this creates acceptable temperature limits of -19°C to -17°C. Therefore, any freezer with a temperature outside this range will be deemed 'out of tolerance'.
Step 2
Check Each Freezer Temperature
Answer
We will iterate through the global data structure holding the temperatures of the freezers. For each temperature, we will compare it to the permissible range (-19°C to -17°C). Any freezer that does not meet this criterion will prompt an output message.
Step 3
Output Message Formatting
Answer
For freezers that are out of tolerance, we will format the output message to clearly state both the freezer number and its temperature.
Example output message for a freezer could be: Freezer {index} is out of tolerance: {temperature}. This structure ensures clarity and maintains proper line separation as per the requirements.
