Question

In Natural language processing stop words removal is an important task. Stop words removal is the process of removing the most common words, for example, common words, such as "an" and "the". Write C program that accepts a sentence and print the sentence after removing all stop words. Using function and string to implement the stop words removal if the list of the stop words are given as below "without", "see", "unless", "due", "also", "must", "might", "will", "may", "can", "much", "every", "the", "in", "other", "this", "the", "many", "any", "an", "or", "for", "in", "an", "an" "is", "a", "about", "above", "after", "again", "against", "all", "am", "an", "and", "any", "are", "aren't", "as", "at", "be", "because", "been", "before", "being", "below", "between", "both", "but", "by", "can't", "cannot", "could","couldn't", "did", "didn't", "do", "does", "doesn't", "doing", "don't", "down", "during", "each", "few", "for", "from", "further", "had" "hadn't", "has", "hasn't", "have", "haven't", "having","he", "he'd", "he'll", "he's", "her", "here", "here's", "hers", "herself", "him", "himself", "his", "how", "how's", "i ", " i", "i'd", "i'l1", "i'm", "i've", "if", "in", "into", "is","isn't", "it", "it's", "its".
