Answer
Identify the ideal temperature and permissible tolerance. The ideal temperature for storing ice cream is -18°C, with a permissible range of -19°C to -17°C (i.e., ±1°C).
Step 2
An output message must be displayed to show the number and temperature of any freezer falling outside tolerance.

Answer
Iterate through the list of freezer temperatures. For each temperature, check if it falls outside the acceptable range (-19°C to -17°C). If it does, format the output message accordingly.
Step 3
The output message for each freezer must be on a single line.

Answer
Ensure that each output message is printed on a new line while specifying the freezer number and its temperature. For example, if Freezer 0 has a temperature of -20°C, then print: 'Freezer 0 is out of tolerance: -20'.
Step 4
No other messages should be displayed.

Answer
Include a control structure to prevent any messages from being output unless they relate to a freezer falling outside of the allowed temperature range.
Step 5
A global data structure holding the temperatures is provided and must be used as part of the solution.
