What would be the value of x after the following statements

What would be the value of x after the following statements were executed?

int x = 10;

switch (x)

{

                case 10:

                x = x + 15;

                case 12:

                x = x + 5;

                break;

                default:

                x = x + 3;

}

5

20

25

30

Solution

Initially after entering the switch statement, as the value of x is 10. The statement enters case 10, so now x becomes 25. But as there is no break statement, it enter the next case statement, now x becomes 20. Now there is a break, so the switch statement is exited. So the final value of x is 30.
