How can structs refer to themselves?

  1. By including a pointer to the struct type within it

  2. By using recursion

  3. Through external functions

  4. Using global variables

The correct answer is: By including a pointer to the struct type within it

Structs cannot have recursive definitions and cannot use recursion. External functions cannot refer to struct types without passing them as parameters, and using global variables can result in ambiguity and cause issues. Therefore, the best way for structs to refer to themselves is by including a pointer to the struct type within it. This allows for easier and direct access to the struct itself.
