switch-case requires break statements before the next 'case' or the
logic falls through to the next case statement which executes...and so on...
So:
When i = 0, i = i + 5 + 2 + 5 + 4;
Thus:
i = 0 + 5 + 2 + 5 + 4 = 16
i (16) is printed out. The loop increments i by 1 (i.e. 17). Then the
switch-case executes. Since i is 17, the default is executed and i
becomes 21.
The actual output is '16,21,' (without quotes). You forgot a comma.
