How to break out of nested loops?

by

No, don’t spoil the fun with a break. This is the last remaining valid use of goto 😉

If not this then you could use flags to break out of deep nested loops.

Another approach to breaking out of a nested loop is to factor out both loops into a separate function, and return from that function when you want to exit.

Summarized – to break out of nested loops:

  1. use goto
  2. use flags
  3. factor out loops into separate function calls

Couldn’t resist including xkcd here 🙂

Goto’s are considered harmful but as many people in the comments suggest it need not be. If used judiciously it can be a great tool. Anything used in moderation is fun.
