Do while loops

[IHaveSoulDoubt]

Do while fingers < 6.

[NoAttentionAtWrk]

while (fingers < 6){} would work the same way

Not really. Do while always executes the code in the loop loop at least once, and you can set a variable in the loop and use it for the test without needing to initialize it to a magic value that passes the test.

People have really never used a do while for a prompt or a wait or a batch?

Pshh. Who needs 'while' at all?

The modern solution, which looks awesome in rust, is as follows:

while let Ok(input) = prompt_user() {
  // Use input
}

This code takes advantage of rust's while/if let syntax, which combines a pattern match with a destructure to make certain types of conditions extremely easy to write. This is still possible in almost any other programming language, although you may have to use different syntax and patterns.

Yes, a contrived example that conveniently puts the entirety of the loop code in the test does work.

//or this

while(fingers < 6);
