C Programming Language on Linux - Word Frequency Program

Please write a Program in C that will accept a text file name as a command-line argument via a main program that will do the following:

First, read the le (rst pass) and create a linked list of words (in their order of occurrence), with the frequency of each word set to 0.

Then, read the le (second pass) and for each word identied, search the linked list, and when found, increment the word frequency by 1.

Now, create a function called PrintList. This will print out each word and its respective word frequency count in the order of appearance.

Next, sort the linked list alphabetically (assuming that each word starts with a letter) and then invoke the PrintList function.

Finally, sort the linked list in decreasing order of word frequency (ignoring the alphabetic order for words with the same frequency) and then invoke the PrintList function.
