What is Correct use of in care of with example?

The phrase "in care of" (often abbreviated as c/o) is used in mailing addresses to indicate that a letter or package should be delivered to a specific person at a different address. For example, if John Smith is staying at his friend’s house, the address might read: "John Smith, c/o Jane Doe, 123 Main St, Anytown, USA." This specifies that the mail is intended for John but should be delivered to Jane's address.
