Don't know how to fix error.

I am trying to fix this matlab code that was written to play a tic tac toe game and I keep getting an error code for syntax and don't know how to fix it. Any help would be appreciated!

Here is the code:

function tictactoe(f_user1,f_user2)

% clear all

% clc

%addpath()

user1=f_user1;

user2=f_user2;

user1wins=0;

user2wins=0;

user2loss=0;

user1loss=0;

ties=0;

user1_forfiet=0;

user2_forfiet=0;

for games=1:1000

%%

board=zeros(3,3);

turn=randi([1 2],1,1);

p=0;

while p==0

turn=turn+1;

if rem(turn,2)~=0

userboard=user1(board,-1);   

else

userboard=user2(board,1);

end

p=legalmove(board,userboard,p);

if p~=3

p=winner(userboard);

end

board=userboard;

end

%%

if p==3

if rem(turn,2)==0

user2_forfiet=user2_forfiet+1;

user2loss=user2loss+1;

user1wins=user1wins+1;

else

user1_forfiet=user1_forfiet+1;

user1loss=user1loss+1;

user2wins=user2wins+1;

end

elseif p==2

ties=ties+1;

elseif p==-1

user1wins=user1wins+1;

user2loss=user2loss+1;

else

user2wins=user2wins+1;

user1loss=user1loss+1;

end

end

user1_stats=[user1wins user1loss ties user1_forfiet]

user2_stats=[user2wins user2loss ties user2_forfiet]


function p=legalmove(board,userboard,p)

if any(size(userboard)~=size(board))

p=3;

elseif sum(sum(abs(board-userboard)))~=1;

p=3;

else

p=p;

end


function p = winner(X)

% p = winner(X) returns

% p = 0, no winner yet,

% p = -1, user 1 has won,

% p = 1, user 2 has won,

% p = 2, game is a draw.

for p = [-1 1]

s = 3*p;

win = any(sum(X) == s) || any(sum(X') == s) || ...

sum(diag(X)) == s || sum(diag(fliplr(X))) == s;

if win

return

end

end

p = 2*all(X(:) ~= 0);

function B=game(B,x)

r=randi(3,1);

c=randi(3,1);

while B(r,c) ~= 0

r=randi(3,1);

c=randi(3,1);

end

if B(r,c) == 0

r=randi(1,3);

elseif B(r,c) ~= 0

c=randi(1,3);

end
B(r,c)=x;

The error is below.

Error: File: Untitled Line: 144 Column: 1

Invalid expression. Check for missing or extra characters.

But I am not sure if there are any other errors after that line is fixed.

What is the input which you have tried?

It doesn't like the blank line after the ...

Get rid of it and have this:

win = any(sum(X) == s) || any(sum(X') == s) || ...
sum(diag(X)) == s || sum(diag(fliplr(X))) == s;

Get rid of all the other blank lines between the lines of code. They're not needed and just make your code longer.
