I've noticed that the command prompt does not accept negative numbers whether the statement (commented below) is commented or left without comments. What is the use of continue? Were there any applications where you had to use them, and, can you provide examples or code snippets?
I find a labeled "continue'' to be very helpful when breaking out of nested loops.
I also use "break" with a label, except from within a switch. Always using labels
is just my conservative nature. I like to see exactly where the code will land.
