Maybe take a look at Getting Started With Windows Programming In C/C++: Key Events[^].

With all the detailed information given in the OP (and all the other posts) I'm not going to assume they are even using Windows. Hell 'they' might be a bot at this point, given previous posts.....and don't call me Shirley! LOL

I have never seen a pong game that does that. The "board" and walls of the game never move. Only the paddle and ball move in the game. The paddle moves only up and down but the ball moves all over the place.

This is the fourth question on this subject. It really is time you started to do some serious research.

C++

int ch;
while ((ch = _getch()) != 27) /* 27 = Esc key */
{
    printf("%d", ch);
    if (ch == 0 || ch == 0xE0)
    {
        ch = _getch();
        printf (", %d - ", ch);
    }
    switch (ch)
    {
    case 0x48:  // up arrow
        printf("up arrow");
        break;
    case 0x50:  // down arrow
        printf("down arrow");
        break;
    case 0x4B:  // left arrow
        printf("left arrow");
        break;
    case 0x4D:  // right arrow
        printf("right arrow");
        break;
    }
    printf("\n");
}

printf("ESC %d\n", ch);
