C program with using data structure

Write a complete C program which comes up with suggestions for a Scrabble-like game. Your program must have take in 1 command-line argument, which is the filename of a list of words which are in the dictionary. (See [login to view URL] for an example word list). Each word in the word list will be on a separate line. You may assume that the word list will be in alphabetical order. Your program will then read in requests from standard input (e.g., the keyboard). Each request will be on a separate line. Each request will begin with a positive integer value, followed by a space, followed by some characters. For example: 6 aba For each request, your program must print out the LONGEST word in the dictionary, which: Begins with the specified letters (e.g., in the example above, the word would have to begin with "aba") Is less than or equal to the specified number in length (e.g., in the example above, the word could not be longer than 6 characters) Has not been print out before. Using the "6 aba" example above, your program should try to find a 6-letter word beginning with "aba", such as "abacus". If it had already given "abacus" for a previous request, then it would be required to give a different word (such as "abased"). If multiple words match the criteria and are the longest, you can return whichever one you like.
