I am trying to build a Tic$-$Tac$-$Toe game in ARM$-64$ that can run on my Raspberry $4.$ I keep getting segment failure. I have been trying to code this for hours and give up$.$ Can you build a Tic$-$Tac$-$Toe game in ARM$-64?$ There needs to be a grid, with numbers like this for example:

$1|2|3$

$---+---+---$

$4|5|6$

$---+---+---$

$7|8|9$

And the player picks a number and the letter X will be there and for player $2$ O will be there.

PLEASE HELP!!!
