WebThen, it enters a while loop that will continue until prt points to NULL. Inside the loop, it prints out the name and price of the drink item that the node is pointing to, using the "->" notation to access the fields of the struct. Finally, it updates the prt pointer to point to the next node in the list, so that the loop can continue to iterate. davis tire and auto gluckstadt
