I am currently creating a Hangman program using Object oriented programming in C++. I tested my words class and it runs perfectly with a sample main that I was using. The classes that I need help with are Hangman and HangmanConsole. I am not sure what to do to get the characters, guesses, and other variables stored and in sync with the rest of the program. I am looking for help or guidance on how to code those classes so, I can get my program running. Here is my code down below:

   #include <iostream>
   #include <fstream>
   #include <ctime>
   #include <string>

      class Words
      {
      private:
        int minlen{0};
       int maxlen{0};
       std::string file_name;

        std::string* choices = nullptr;
        int count{0};

    public:

        Words (int min, int max, std::string fName)
        {
            minlen = min;
            maxlen = max;
            file_name = fName;

            this->load_words();
            srand( time(NULL) );
        }

        ~Words()
        {
            delete [] choices;
        }

        int getCount()
        {
            return count;
        }

        void display_list()
        {
            for(int i = 0; i < count; i++)
            {
                std::cout << choices[i] << '\n';
            }
        }

        void load_words()
        {
            std::ifstream fwords(file_name);

            if(!fwords)
            {
                std::cout << "Cannot open file\n";
                return;
            }
           // This counts the words (1st file read)
            std::string temp;
            count = 0;
            while(fwords >> temp)
            {
                // Filter words
                if(temp.length() == minlen or temp.length()== maxlen)
                    count++;
            }



            // Setting up the array
            choices = new std::string[count];
            fwords.close();

            // Loading the array (2nd File read)
            fwords.open(file_name);
            int index{0};
            while(fwords >> temp)
            {
                if(temp.length() == minlen or temp.length() == maxlen)
                {
                    choices[index] = temp;
                    index++;
                }
            }
            fwords.close();
        }

        std::string pick_word()
        {
            if (count == 0)
            {
                return "Zero words available to select from";
            }

            return choices[rand() % count];
        }
    };

  class Hangman
  {
   private:
      char word[40];

      {
         word = w; // This will be used to store the generated word
         progress = p;
         word_length = wlen;

      }
