Can someone help me with this c++ code?Instructions: This assignment uses pointers to perform something done often in computer applications: the parsing of text to find “words” (i.e., strings delineated by some delimiter). Assume you are working in the marketing department of a company that sells computers and accessories. Your team has been tasked with determining how customers perceive your products based on customer surveys. The questions in the surveys are open-ended. That is, customers write product reviews as paragraphs about their perceptions of your products. Your job is to prepare the customer responses to facilitate a sentiment analysis.Program executes without crashingAppropriate Internal Documentationmain() Declares variables appropriately (uses pointers where needed for tokenization and creates a Review object for storage of Words) Prompts user to enter a filename with appropriate error checking Contains a loop to tokenize each word in the product review using the strtok_s function Calls the AddWord function in the Review class (passing in each token)Review class: Constructor(s) as appropriate Data members: vector of Word objects Functions: AddWord, DisplayWords, getters/setters as appropriate Word classConstructor(s) as appropriateData members: word and frequencyFunctions: ConvertToLowerCase, getters/setters as appropriate Processing:After an entire product review is read in to your character array, print out the entire review insentence form. Next, tokenize each word using the strtok s function described above. As eachword in the review is tokenized, call a function in the Review class (passing in the token pointerthat is returned from the strtok s function) to add the new word to the Review object's vector ofwords. Call this function AddWord.Before storing the word as an object, the AddWord function in the Review class should searchthe existing vector of Word objects to determine if the word already exists in it. To determine ifthe word already exists in the vector of Word objects, you should loop over the vector andPage 21 of 38CSIS 112compare each Word's "word' with the new word to be added. If it does not already exist, thefunction should create a new Word object (passing in the pointer to the word as a parameter tothe constructor of the Word class), assign it a frequency of 1, and add the new object to thevector in the Review class. If the word does already exist in the vector, you should merely call afunction in the Word class that will increase the frequency of that Word object by 1.One note of caution: C++ is case sensitive. Therefore, the word "thanks" is considereddifferent from the word "Thanks'". Semantically, they are the same word. Therefore, we onlywant to store one instance of the word. My recommendation is to create a function in the Wordclass that will convert the word into lowercase before assigning it to the "word' data member.The constructor of the class would be an excellent place to call this function (i.e. before the wordis ever stored in the member variable). To summarize: store only the lowercase versions of eachword in the Word objects.For information on how to convert a character array into all lowercase characters, this blog onStackOverflow is a good resource: https://stackoverflow.com/questions/27054353/c-converting-array-of-char-into-lower-caseBe sure to cite it in the resources section of your program if you use any of this code.Naturally, in real-life, you would want to eliminate words such as "the," "an," "and," “but," "or,"etc. You would also want to only include root words. That is, there is no need to store "enjoy,""enjoyed," and “enjoying" as separate words. This process is called "stemming." However,pruning your list to exclude words with no meaning and including only root words are tasks thatare beyond the scope of this assignment. Therefore, your vector should contain a unique list ofall the words in the product review with their respective frequencies.Output:The output of the program should be a listing of all of the words in the review with a count oftheir frequencies. You do not have to assign meaning to any of these words as would be requiredin a full-blown sentiment analysis. However, this program performs the necessary first steps inpreparing the data for a more extensive investigation of consumer sentiment.Here is an example of how your output might look: The Program: Setting up classes and understanding tokenizationThe first step in a sentiment analysis is to perform text mining to parse sentences in a productreview document into words and store them in an array (or vector) along with their frequencies.Tokenization:The process of parsing sentences into words is called tokenization. To tokenize a sentence intowords, use the C++ function strtok s(). [Note: do not try to use the C++ strtok function becauseit has been deemed unsafe and has therefore been deprecated.]Your client code (main()) should contain a character array into which you will read an entireproduct review from a file.
