Answers to follow-up questions

Programming term for count = count + 1

The one-word programming term is increment.
The statement increases the value stored in the variable by 1 and assigns the updated value back to the same variable.
This pattern is very common and can also be written using shorthand operators such as count += 1; or count++;.

Is .padEnd(2, "0") necessary?

Yes, .padEnd(2, "0") is needed to handle cases where the pence value has fewer than two digits.

For example:

• If penceString = "5p", removing "p" gives "5"
• substring(length - 2) would return "5" (only one digit)

Without .padEnd(2, "0"), the output would be £0.5.
With .padEnd(2, "0"), it becomes £0.50.

So .padEnd ensures the pence part always contains exactly two digits, which is required for correct currency formatting.
