C++ Program wont quit, using switch case

I'm writing a tic tac toe program that plays throuh the terminal/console After Player 1 or 2 wins, I give the choice for the user to play again, 1 = play again, 2 to quit. However, entering 2 to quit doesnt work

//tie check, replay, use pointer notation
#include <iostream>
using namespace std;

void initialize(char [][3]);
void player1(char [][3]);
void player2(char [][3]);
void display(char [][3]);
char check(char [3][3]);
int main()
{
    char board[3][3];
    char end = '*';
    int row1, column1, row2,column2;
    bool replay = true;
    //replay loop
    do
    {
        //set board to *
        initialize(board);
        //game loop
        display(board);
        do 
        {
            //player 1 turn
            player1(board);

            //check if player 1 won
            end = check(board); 
            if(end != '*')
            {
                int input;
                /* winner!*/
                cout << "Player 1 Won!\n";
                do
                {
                    cout << "Play Again?\n1.Yes\n2.No\nEnter 1 or 2: ";
                    cin >> input;
                    if (input > 2 || input < 1)
                        cout << "Invalid Option\n";

                }while(input > 2 || input < 1);

It looks like your switch statement has character literal values ('1' and '2') rather than int values of 1 and 2.
