while-loop

问题 I'm working on a program that is a guessing game. However the loop for identifying whether an individual guessed the correct number fails to even begin I get this: Player 1: Type a number between 0 and 99 and press return: 1 Type the number of guesses that player 2 gets and press return: 1 Sorry you are out of guesses. You lose. The loop terminates before it even begins and I can't figure out how to make it work. This is the code for the loop: printf( "Type the number of guesses that player 2

问题 I am 11 and just started programming. I was trying to use a while loop and I want it to display the answers in blocks instead of one huge chunk. So i tried to use a setTimeout but it would just display the first line after a second then instantly display the rest as a huge chunk. Also it would then use the number 9 as the temp variable even though i got no idea where that came from.Thanks in advance. I would like to keep the while loop in the code because I am learning how to use them , so if

问题 Basically (hopefully) I want to record a video stream from a webcam and save it in a specific directory, then kill that when a user inputs some numbers.

问题 I am trying to run a program that outputs the sum of every digit of an entered in integer. How would I go about reading the number and outputting each digit? Example: Input is 4053 the output would be "4+0+5+3 = 12". import java.util.Scanner; public class Digits{ public static void main(String args[]) { //Scans in integer Scanner stdin = new Scanner(System.in); System.out.println("Enter in a number: "); int number = stdin.nextInt(); //Set sum to zero for reference int sum = 0; int num =

问题 Is there an idea of a while loop in Camel? We are using Camel for doing batch processing (not really the remit of an ESB I know). I want to keep checking on the status of something else whilst I am processing messages in the ESB. I can only find a loop that loops for a defined number of times, i.e. for testing or a quartz timer that will check every x seconds. Neither of these are really suitable. Any suggestions, or am I asking for something simply outside of the remit of an ESB? 回答1: What

问题 I need to validate the user output for three different prompts and thought this would work but it is not. The first prompt need to validate any of the 8 states and territories of Australia. The second prompt needs to validate that the user has entered a whole number. The third prompt needs to validate that the user has entered a negative or positive number that can be whole or has decimals. Then the whole thing needs to loop over again so the three prompts can be asked again. So it can build

问题 I'm brand new to Javascript and teaching myself. I'm trying to setup a function that will write each of the elements of the array AmericanCars with a space between the elements. I have it working so that when I use .innerHTML=AmericanCars[Index Position] plus a non-breaking space, I can write one element of the array. Now I'm trying to loop through it with a while loop, but I just get an output of "undefined." How can I get .innerHTML to write out each of the elements of an array with a space

问题 *This has to be done in javascript, not jQuery. What I'm trying to do is grab the innerText of the h4 tag when <a> with the class btn-blue is clicked. I realize that I could do: element.parentElement.previousElementSibling.children[0].innerText; but I'm really wanting something more flexible. This is what I have so far, and it does work when I run it in the console (chrome), but as soon as I add it to the site, it doesn't pull in the innerText of the h4 tag. HTML <div class="border-box
