Given the following code and flag = 2

(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:

       // Create an array with std::array
       array <array <int, COLUMN>, ROW> myArray =
       {{
             {1,2,3,4,5},
             {10,20,30,40,50},
             {100,200,300,400,500},
             {6,7,8,9,0}
}}; (Points : 5)
