can any answer these question ASAP?

1. (TCO 3) Given the following code and flag = 2, what is the value of x after the code executes?
 
int x = 0;   
switch (flag)
{
case 0:
       x++;
       break;
case 1:
case 2:
       x++;
case 3:
       x++;
       break;
case 4:
       x++;
case 5:
case 6:
       x++;
case 7:
       x++;
       break;
default:
       break;
}(Points : 5)        x
will be 0.
       x
will be 1.
       x
will be 2.
       x
will be 3.
