while-loop

What would a very simple while loop statement be that would continue the below program until the user types "exit"? For example, while response = (!'exit') continue file else break print ('Thank you, good bye!') #I know this is completely wrong, but it's a try! My file so far: #!/usr/bin/python friends = {'John' : {'phone' : '0401', 'birthday' : '31 July', 'address' : 'UK', 'interests' : ['a', 'b', 'c']}, 'Harry' : {'phone' : '0402', 'birthday' : '2 August', 'address' : 'Hungary', 'interests' : ['d', 'e', 'f']}} response = raw_input("Please enter search criteria, or type 'exit' to exit the

This question already has an answer here: How to handle infinite loop caused by invalid input (InputMismatchException) using Scanner 5 answers boolean z = false; do { try { a = sc.nextInt(); z = true; } catch(Exception e) { } } while(!z); Try this. If you try an integer the first time it executes properly. However if you enter the wrong type of text it turns into an infinite loop even if you enter an int next and skips assigning the boolean value to true. Why is this? Your problem is from not handling the end of line token and so the scanner is left hanging. You want to do something like so:

I have a code that runs many iterations and only if a condition is met, the result of the iteration is saved. This is naturally expressed as a while loop. I am attempting to make the code run in parallel, since each realisation is independent. So I have this: while(nit<avit){ #pragma omp parallel shared(nit,avit) { //do some stuff if(condition){ #pragma omp critical { nit++; \\save results } } }//implicit barrier here } and this works fine... but there is a barrier after each realization, which means that if the stuff I am doing inside the parallel block takes longer in one iteration than the

I'm trying to send multiple post within a do while loop but the result is not added <script type="text/javascript"> function action() { var initval = 1; var endval = 5; do { var action_string = 'txtuser=someone'; $.ajax({ type: "POST", url: "http://localhost/js.php", data: action_string, success: function(result){ $('div#append_result').append(initval + ',<br/>'); } }); initval++; } while (initval <= endval); } </script> The Output is: 5, 5, 5, 5, 5, and I need the output to be: 1, 2, 3, 4, 5, Due to the async nature of AJAX, by the time your success function runs for any of the resulting AJAX

I currently have a working parser. It parses a file once(not what I want it to do) and then outputs parsed data into a file. I need it to keep parsing and appending to the same output file until the end of the input file. Looks something like this. try { // my code parsing the data and appending to eof of output. (works) } catch (EOFException eof){ } Everything is done except the while loop. It only parses once when I need it to keep parsing. I'm looking for a while loop function to reach eof. I'm also using a DataInputStream. Is there some sort of DataInputStream.hasNext function?

I'm trying to reduce a float by a time value, i'm using Unity and stopping time Time.timeScale = 0f; so can not use Time.deltaTime so using 'Time.realtimeSinceStartup' in a while loop, i read in the master volume variable from a global script that the player can set in game between 0 - 1 so say i read in 0.6 and i want to lower the volume to 0 in 2 second how do i get the percentage to keep reducing the volume by ? Here is my code .. private IEnumerator VolumeDown () { float volumeIncrease = globalVarsScript.musicVolume; float volumePercentage = ??; float newLerpEndTime = Time

/// infinite loop?? $x=1; while($x=9){ echo $x; $x++; } i dont understand the reason behind, why the above code causes infinite loop in my opinion above code should output "9" once. but it outputs endless 999999999...... at first (when x is equal to 1) while statement is false so nothing happens, then x becomes 2 but again while statement is false; So when x becomes 9 while statement is true so it should echo 9 then we add 1 due to x++; and it becomes 10 so while statement becomes false but as i see it doesnt because it continues to echo 9999999....... pls enlighten me regarding the above code
