N this exercise you will design and implement a basic spell checker program. Specifically, you will write a program that opens a text file, processes each word separately andchecks its spelling against a dictionary file of words to determine if it is a valid Englishword. All of your code should be placed in one file named spellChecker. c. The programaccepts the test file name (e. g., wordFile1.txt) as a command line argument so that itis executable like this: ./spellChecker wordFile1.txtYour program should open the input file and spell check each individual word. Youmay assume that each word is separated by some whitespace, and you may assume thatthere are no multiline or hyphenated words. Ignore all punctuation characters (, ; . ?!), white space and new line character when spell checking. Use the dictionary available on the CSE system. The dictionary is contained in aplaintext file named "american", which contains thousands of english words (one oneach line) to spell check each word. You will have to use thefull path of the fileto open it: /usr/share/dict/american. While reading each word from the dictionaryfile, ignore the new line character. Your output should produce a list of misspelled orunrecognized words (words not contained in the dictionary file).
