do-while

问题 I am learning QT these days and I wanted to test do while loop , the actual login works in normally, but in QT the application freezes .. I have defined randnum and guess in the header file ( public ) void MainWindow::on_pushButton_clicked() { srand (time(NULL)); randnum = rand() % 10 +1; do { guess = ui->spinBox->value(); if (guess < randnum) { ui->label->setText("try something big"); } else if (guess > randnum) { ui->label->setText("try something small"); } else ui->label->setText("YAY?");

问题 I'm creating a very simple number guessing game for a school project and am having trouble with the repeating main menu. I created it using a do-while loop and the problem I'm having is that the menu selection variable is an int , and so when I (or the user) enters a non-int input by accident when selecting from the menu the }while(condition) at the end of the main loop can't catch it and the program repeats infinitely. Conversely if you enter an invalid int at menu selection the program

问题 So I'm trying to ask the user if they would like to repeat my program and I am getting a weird result now and then. It doesn't happen everytime and I havn't been able to figure out what triggers it. To me it looks like it is assigning the 'return' after I enter 'q' to repeatProgram instead of the 'q' but I have no Idea why. The output when it works: to exit enter q, to continue enter y. s you've entered s, that isn't a valid option. The output when it fails: to exit enter q, to continue enter

问题 I am writing an application to compare each item on listbox1 to all items on listbox2. If the item is found, then remove it from both lists. The goal is to only have the items that were not found remain on both lists. The problem is, the application just hangs and I never get any results. I looked at my code several times and I cannot figure out what's going on (programming noob I know...). Can anybody help me with this? Code Snippet: Private Sub Button2_Click(ByVal sender As System.Object,

问题 This question is a follow-up from this link Java SE do while loop issues This is an application asking for a room's name then second prompt to ask for its dimensions to perform some calculations. right after everything has been done, the application should be able to return back to the first prompt asking for the name of room etc. class Room { private String name; private double length; private double width; private double height; public Room(String r, double l, double w, double h) { name = r

问题 I'm Writing a program for Billing System. I'm using do-while loop in my program. And the program is executed according to user input. If the user want to continue the execution, the program will be continue. But I Got a prob in Execution. I was trying my logic in simple do-while loop. The same Problem arises for simple do-while loop also. Problem is: If the input is yes, the program does not get the further input from user. That simple do-while loop is: #include <stdio.h> main() { int c; char

问题 Please help with the swtich case need for a game public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Please Enter a number"); int day = input.nextInt(); switch(day) { case 1: System.out.println("1 Microphone"); break; case 2: System.out.println("2 Loud Speakers 1 Microphone "); break; case 3: System.out.println("3 Keyboards 2 Loudspeakers 1 Microphone "); break; case 4: System.out.println("4 Java Books 3 Keyboards 2 Loudspeakers 1 Microphone");
