A more thorough explanation:

Definition: c/o is an abbreviation that stands for "care of." It is used to indicate that a letter or package should be delivered to someone at an address where they are temporarily staying or where they do not have a permanent address. Example: If you are sending a letter to a friend who is staying at a hotel, you might address it like this:

John Smith
c/o The Plaza Hotel
123 Main Street
New York, NY 10001

This tells the hotel staff to deliver the letter to John Smith, who is staying at their hotel. Explanation: The abbreviation c/o is commonly used in mailing addresses to indicate that the recipient is not the primary resident of the location. It is often used for people who are staying at a hotel, a friend's house, or a temporary residence. The example shows how to use c/o in a mailing address to ensure that the letter is delivered to the correct person.
