*** PLEASE LEAVE DETAILED COMMENTS EXPLAINING WHAT YOU ARE DOING ***

Enter the file name: words.txt Output: encode/decoded words are written to file: words.txt.sft The program reads the content of the file and stores the words in an array of strings, the program then finds the pairs of encoded/decoded words and writes them to the output file 1. Name your program file_search.c. The output file name should be the same name as the input file but with an added extension of .sft. In this example, the original file name is words.txt. The output file name is then words.txt.sft. Assume the file name is no more than 100 characters. Assume the length of each line in the input file is no more than 100 characters. Assume the input file contains no more than 1000 words,. 2. In the program, use the shift function (provided in shift.c) to help search for pairs of encoded/decoded words. The function shifts the alphabetical letters message in by shift amount
