Exercism #43: Phone Number Analysis

Learning Goal

Tuples

Relevant Information

Tuples in C# is a way of organizing data to hold 2 or more fields of any type. Each field is separated by commas within parentheses.

Task 1

Your analysis should return 3 pieces of data

1. An indication of whether the number has a New York dialing code ie. 212 as the first 3 digits
2. An indication of whether the number is fake having 555 as a prefix code in positions 5 to 7 (numbering from 1)
3. The last 4 digits of the number.

Implement the (static) method PhoneNumber.Analyze() to produce the phone number info.

Task 2: Detect if a phone number has a fake prefix code (555)

When do you choose a tuple over a custom type?
