Data Structures
In this assignment, you will write a spell-checker for text files. Your program should take a file name as a command-line argument and check the file for any misspelled words. If a word is misspelled, the program should output a line number and line containing the word and highlight the word by printing a sequence of carets (‘^’) underneath it on the next line.
Your program should consider any sequence of one or more letters separated by whitespace or punctuation a word. Do not attempt to handle words with apostrophes or other intra-word accents correctly: e.g. “you’re” should scan as “you” and “re”. The Character class has a method isLetter which you can use to determine whether a char is a letter in the alphabet.
The file words.txt contains a list of valid words. Use this file as your dictionary. For each word in the input file, scan through words.txt until a matching word is found; if no matching word is found, consider the word misspelled.
See below for words.txt
