All of my code works with what I have but I am struggling to find a way to make the matches made in the game stay visible to the user so they don't have to look back at their past inputs. I already tried to start figuring out my problem but I just don't know how to continue or if what I have is correct.

#include <windows.h>
#include<iostream>
#include <cstdlib>

string firstName;
char difficuty;
int column, row, row1Value, column1Value, row2Value, column2Value, matrix[4][4];
int menu;
bool again = true;
bool matrix2[4][4];
HANDLE color=GetStdHandle(STD_OUTPUT_HANDLE);

public:

void start()
{
while(again){
//Main Menu
SetConsoleTextAttribute(color, 9);
cout << "Welcome to Memory - The Card Game" << endl << endl;

// Select game

All of my code works
Perhaps, but what you posted won't even compile. You seem to be missing four(!) closing braces after line 113. Thanks TheToaster for posting with code tags. It looks like you're missing a whole section for intermediate games.

I am struggling to find a way to make the matches made in the game stay visible to the user so they don't have to look back at their past inputs.
I think that is what matrix2 is for. Cells are true if the corresponding entries in matrix have been guessed correctly so far.

To simplify the code, I created a display() method that displays the board. It shows '*' if the position is hidden and the card value if the position has been exposed.

As you play, the code exposes the two cards that you guess. If the cards match, it leaves them exposed. Otherwise it hides them again.

I changed easyLoop() and easyMatch() to Loop() and Match(). These same functions should be used for the intermediate game. You should just add one member variable to the class that says how big the grid is (4 for easy, 6 for intermediate) and then the code should use that variable to initialize the board, display the pieces etc.

I also noticed that you call the various functions over and over rather than having loops. I changed that. I also moved some of the logic around slightly. Look at this version and compare it to your original code. I put a loop in easyLoop(). When you finish the game, I let the loop in start() print the menu again.
