Pulling out parts of a phone number

You can now go back to the phone number example from the previous chapter. You developed a pattern to extract the parts of string that looked like phone numbers, and now you have the skills to pull out the pieces of the number. Let's see if you can put your skills together to output the first phone number in each string in a common format.

Instructions
100 XP

We've put the pieces of your pattern in your workspace, along with some text containing phone numbers in the variable contact.

  • phone_pattern is the pattern you developed in the last chapter. Edit it to capture() each sequence of numbers.
  • Use str_match() to grab all the pieces into phone_numbers.
  • Put together the pieces with str_c() into the format (XXX) XXX-XXXX.
