Increment, and Decrement not acting as expected

I am writing a console based game in C++ and I have gotten to the point of moving the player by arrow keys, but they x--, and y-- do not change the values of x or y, I have tried other configurations like x -= 1, and x = x-1, but neither have worked

(i have also tried the _Game struct as a class, with no better results)

my code is

#include <iostream>
#include <unistd.h>
#include <termios.h>
// #include "colorlib.hpp"
// #include "dict.hpp"

using namespace std;
// using namespace UnixColor;
// using namespace Dict;



// dict colors = initColors();
// string red = getC(colors, "red");
// string gray = getC(colors, "gray");

int x, y;

struct _Game {
    int board[5][5] {
        {0, 0, 0, 0, 0},
        {0, 0, 0, 0, 0},
        {0, 0, 0, 0, 0},
        {0, 0, 0, 0, 0},
        {0, 0, 0, 0, 0}
    };

    void checkBoard() {
        for(int i = 0; i < 5; i++) {
            for(int o = 0; o < 5; o++) {
                if(board[i][o] == 1) {
                    board[i][o] = 0;
                }
            }
        }
        board[y][x] = 1;
    }

    void bprint() {
        checkBoard();
        for(auto var : board) {
            for(int i = 0; i < 5; i++) {
                // cout << var[i];
                if(var[i] == 0) {
                    // cout << gray << "{}" << RESET;
                    cout << "{}";
                }else if(var[i] == 1) {
                    // cout << red << "[]" << RESET;
                    cout << "[]";
                }
            }
            cout << endl;
        }
    }

};
