Please Help:- Write a c++ program:- Process the attached file of words to determine all the 7-letter words that start with "qu" or "ch" and have the same last 5 letters, such as "charter" and "quarter". Use the class template below. Fill out the Questions in class & int main() function. class Word { std::string word; // the word bool startqu; // true if the first 2 letters of the word are q and u bool startch; // true if the first two letters of the word are c and h int length; // length of the word Word *next; // a pointer to another instance of Word public: Word(std::string& w); // constructor bool startWithqu() const; // startqu accessor bool startWithch() const; // startch accessor bool prefixEqual(std::string& pfx) const; // is this word's prefix equal to the passed string bool suffixEqual(std::string& sfx) const; // is this word's suffix equal to the passed string Word *getNext() const; // next accessor Word *setNext(Word *n); // next set accessor std::string getWord() const; // word accessor }; Word::Word(std::string& w) { /* constructor */ /* initialize all member variables */ /* set the value of the startch and startqu flags */ } bool Word::startWithch() const { /* startch accessor */ } bool Word::startWithqu() const { /* startqu accessor */ } bool Word::prefixEqual(std::string& pfx) const { /* is this word's prefix equal to the passed string */ } bool Word::suffixEqual(std::string& sfx) const { /* is this word's suffix equal to the passed string */ } Word *Word::getNext() const { /* next accessor */ } Word *Word::setNext(Word *n) { /* next set accessor */ /* return the new value */ } std::string Word::getWord() const { /* word accessor */ } int main() { const int TARGET_LENGTH = 7, START = 2; std::string fileName = "/Users/danevans/Downloads/7ltr-words.txt"; std::ifstream file; std::string word, sfx; std::string sent = "sentinel"; Word *chwords, *quwords, *qusq, *chsq, *obj; int chsiz, qusiz, count; file.open(fileName); if (!file) { cout << "unable to open file: " << fileName << endl; return -1; } /* create sentinel words to start the ch list and the qu list */ /* read and process each word */ while (getline(file, word)) { /* filter out words whose length is not seven letters */ /* construct a Word object from the input word */ /* if the Word instance starts with qu, add it to the qu list */ /* else if the Word instance starts with ch, add it to the ch list */ /* else free the object since it doesn't start with qu or ch */ } /* finish with the file */ /* drop and free the sentinel on each of the lists */ /* loop through the ch list */ while (0 != chsq) { /* get the 5 charactder suffix of the current ch Word */ /* loop through the qu list */ while (0 != qusq) { /* if the qu suffix is equal to the ch suffix, count it and display the words */ } } /* display the results of the searches */ cout << "found " << (chsiz + qusiz) << " seven letter words starting with \"qu\" or \"ch\"" << endl; cout << "found " << count << " matches" << endl; /* free the ch list */ /* free the qu list */ return 0; }
