Assuming you are doing this for exercise:

It'd be better to unindent all the switch/case
blocks for the entire function so more functions
fit on single lines

	switch (foo) {
	case bar:
		{
			...;

should be:

	switch (foo) {
	case bar: {
		...;

goto exit; might as well be break; and remove
the exit label too.
