I need a C program that will take the input of two txt files, put all the contained words from both txt files into a linked list. Compare all the words in the list, and then output unique common words that both txt files have in ascending sorted order based on the word field using the strcmp() function. Please use dynamic memory allocation utilizing the malloc function for the linked list. Please show all code for this, thank you!

Please provide comments on each important function and event in the code so I can better understand it, thank you!
