Question

In this task you will work with the linked list of digits we have created in the lessons up to this point. As before you are provided with some code that you should not modify:

  • A structure definition for the storage of each digit's information.
  • A main() function to test your code. 
  • The functions createDigit(), append(), printNumber(), freeNumber(), readNumber() and divisibleByThree() (although you may not need to use all of these).

Your task is to write a new function changeThrees() which takes as input a pointer that holds the address of the start of a linked list of digits. Your function should change all of those digits in this linked list that equal 3 to the digit 9, and count how many replacements were made. The function should return this number of replacements.
