Given the following switch structure, where x is an int:

switch (x + 1)

{

case 3:

x += 2;

break;

case 5:

case 4:

x += 3;

break;

case 7:

case 6:

x += 1;

break;

}

If x = 4, what will be the value of x after the switch statement executes?

please explain ur answer, this question must be solved by hand!!
