Solution

The value of y will be 2 after the execution of the switch statement.

Here's the step by step explanation:

  1. The switch statement evaluates the expression x + 3, which equals to 3 + 3 = 6.

  2. It then checks for the case that matches the value 6. It finds case 6 and executes the statement y = 0;. Now, y is 0.

  3. However, there is no break statement after case 6, so it continues to execute the next case, which is case 7. But case 7 does not match the value 6, so it is skipped.

  4. Finally, it reaches the default case. The default case is executed if no other case matches. Here, it executes the statement y += 1;, which is equivalent to y = y + 1;. Since y was 0, now y becomes 0 + 1 = 1.

  5. After the switch statement, y is 1.

  6. However, there is a mistake in the question. The default case should be executed only if no other case matches. But in this code, it is executed even after case 6 matches. This is because there is no break statement after case 6. If we add a break statement after case 6, then the default case will not be executed, and y will remain 0 after the switch statement. But as per the given code, y will be 1 after the switch statement.
