This is a mastermind game. I was trying to make sure that my twoD array was beinga ssigned right by printing it out real quick before i use it to draw a board in the console. For some reason im gettin these errors and i dont even have a clue how to fix it. Help please

Code:

```
#include <iostream>
#include <iomanip>
#include <ctime> // For time()
#include <cstdlib> // For srand() and rand()
using namespace std;
int rowCounter = 0;
int colCounter = 0;
char twoDArray[8][4];
const int guess_rows = 8;
const int guess_cols = 4;
int *getRandomNumbers(int);
char setColor(int num);
void promptUser(char guess[4], int n);
bool endGame(char guess[4], char answer[]);
void copyToTwoDArray(char guess[4], char twoDArray[8][4],int n);
void showArray(char [][guess_cols], int );
int main()
{
char guess[4];
char answer[4];
char playAgain = 'Y';
bool success;
bool win;
int guesses;
char vote;
int *numbers;
do
{
success = false;
guesses = 0;
cout << endl;
numbers = getRandomNumbers(4);
for(int count = 0; count < 4; count++)
{
cout << numbers[count] << endl;
answer[count] = setColor(numbers[count]);
cout << answer[count] << endl;
}
cout << endl;
while (!success && guesses < 9)
{
promptUser(guess, guesses);
copyToTwoDArray(guess,twoDArray, guesses);
success = endGame(guess, answer);
guesses++;
}
if(success)
{
cout << "You guessed the correct answer" << endl;
cout << "The correct answer was: " << answer[0] << answer[1] << answer[2] << answer[3] << endl;
