verifyExists function is throwing a crazy amount of errrors

Question

I'm making a wordle program for a class assignment and the basic concept is to load all 5 letter words in the English language from a text file into an array, then pick one randomly to be the correct one, and I have that part correct (probably isn't that efficient but it works for now). I need to verify the user input that the 5 letter word they entered is actually in that array. For example they enter "djghd", which isn't a word that would be in that array. here is the code that I used:

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

using namespace std;

bool verifyExists(string word, string verifyArr) {

  for (int i = 0; i < 2315; i++)
    {

      if (word == verifyArr[i])
        {

          return true;

        } else {

          return false;

      }

    }

}

void playGame(string word, string arr) {

  string guessWord;

  cout << "Ok. I am thinking of a word with 5 letters." << endl;
  cout << "What word would you like to guess?" << endl;
  getline(cin, guessWord);
  verifyExists(guessWord, arr[2315]);
  cout << guessWord << endl;
}

int main() {

  string word;

  int loop = 0;

  string wordArray[2315];
  
  ifstream myfile ("proj1_data.txt");

  cout << "Welcome to UMBC Wordle" << endl;

  if (myfile.is_open())
    {

      cout << "Your file was imported!" << endl;
      cout << "2315 Words imported" << endl;

      while (! myfile.eof())
        {
          getline(myfile, word);
          wordArray[loop] = word;
          loop++;
        }

      myfile.close();

    }

  int max;

  max = 2315;
  srand(time(0));
  string chosenWord = wordArray[rand() % max];

  playGame(chosenWord, wordArray[2315]);

  return 0;
}

When I try to compile it, it throws a ton of errors (Which might just be the compiler I'm using) and i need to use infinite scroll to get through them all so I cant add them here. They only show up after I added the verifyExists function so I know that's the source of the error I just don't know what is causing it. I'm also not allowed to use pointers so that makes it difficult. Any help is greatly appreciated, thank you.

Everything about this code is wrong. The #include statements are wrong. The way you load the file is wrong. The way you use the array is wrong. The logic of the game is wrong. It needs a complete rewrite to do things the right way.

Try something more like this instead:

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

using namespace std;

bool verifyExists(const string &word, const vector<string> &verifyArr) {
  for (size_t i = 0; i < verifyArr.size(); ++i) {
    if (word == verifyArr[i]) {
      return true;
    }
  }
  return false;

  // Alternatively, use std::find() instead...
  // return find(verifyArr.begin(), verifyArr.end(), word) != verifyArr.end();
}

void playGame(const string &chosenWord, const vector<string> &wordArray) {
  string guessWord;
  cout << "Ok. I am thinking of a word with 5 letters." << endl;
  cout << "What word would you like to guess?" << endl;
  getline(cin, guessWord);
  if (guessWord == chosenWord) {
    cout << "You guessed correct" << endl;
  } else {
    cout << "You guessed incorrect" << endl;
  }
  if (verifyExists(guessWord, wordArray)) {
    cout << "Your guess exists in the list" << endl;
  } else {
    cout << "Your guess does not exist in the list" << endl;
  }
}

int main() {

  cout << "Welcome to UMBC Wordle" << endl;

  vector<string> wordArray;

  ifstream myfile ("proj1_data.txt");
  if (myfile.is_open()) {
    string word;
    while (getline(myfile, word)) {
      wordArray.push_back(word);
    }
    myfile.close();
  }

  if (wordArray.empty()) {
    cout << "No words were imported!" << endl;
    return 0;
  }

  cout << "Your file was imported!" << endl;
  cout << wordArray.size() << " Words imported" << endl;

  srand(time(0));
  string chosenWord = wordArray[rand() % wordArray.size()];

  playGame(chosenWord, wordArray);

  return 0;
}
