Question

c++. I'm working on a hangman game. It has to utilize a class. It should show the number of attempts that have been made, the length of the word represented by dots, and then the alphabet. There also needs to be input validation. If the word was horse, the very first attempt at the user guessing should display " 1 ..... choose: abcdefghijklmnopqrstuvwxyz ". As the user guesses letters, the number of attempts should go up, the letter should be changed to a " . " in the alphabet, and if the letter was within the word that was generated, then the dots would be changed to that letter. With the previous example, if the user entered " h " then the screen would display " 2 h.... choose: abcdefg.ijklmnopqrstuvwxyz " I've got a string vector of the generated word, but I'm not sure if I need a second vector full of dots that equal the length of the first and if I need a vector for the alphabet.

This is what I have so far.

#pragma once

#include <vector>

#include <string>

using namespace std;

class wordguess {

private:

    int attempts;

    int location;

    string random_word;

    vector<string> string_vector;

public:

    void get_words();

    void generate_random();

    void get_guess();

};

#include "wordguess.h"

#include <iostream>

#include <fstream>

#include <string>

#include <vector>

#include <time.h>

#include <stdlib.h>

using namespace std;

void wordguess::get_words() {

    ifstream in("wordpool.txt");

    string str;

    while (getline(in, str)){

        if(str.size() > 0) {

            string_vector.push_back(str);

        }

    }

    in.close();

    // for (int i = 0; i < string_vector.size(); i++) {

    // cout << string_vector[i] << " ";

    // }

}

void wordguess::generate_random() {

    srand(time(0));

    int r = string_vector.size() -1;

    int random = rand() % (r + 1);

    random_word = string_vector[random];

    cout << random_word;

}

void wordguess::get_guess() {

    

}
