I'm using Xcode on MacOs and language is C++
here's the input code.

void Input()
{
if (getchar()
({

switch _getch();
{
case 'a':
dir = LEFT;
break;
case 'w':
dir = UP;
break;
case 's':
dir = RIGHT;
break;
case 'd':
dir = DOWN;
break;
case 'x':
gameOver = true;
break;
}
}
}

Answer 1

It's kind of confusing...

On the third line, I don't know what you tried to achieve but you probably just confused a starting round bracket with a closing one :/
