user-input

问题 I have been going through C++ Primer Plus and I am working on the programming challenges in it using Visual Studio Code since there were weird issues with Visual Studio 2017. I have looked at a lot of other similar posts but the solutions there don't work for me. For example I tried putting a breakpoint at the main() function's closing curly brace, putting in cin.ignore() at the end before return 0. But none of that works. Here is the code. #include <iostream> using namespace std; int main()

问题 largest_so_far = None smalest_so_far = None value = float(raw_input(">")) while value != ValueError: value = float(raw_input(">")) if value > largest_so_far: largest_so_far = value elif value == "done": break print largest_so_far I think problem with this is that done is string while input is float type. I have also tried it running using value = raw_input(">") instead of float(raw_input(">") but that prints the result as done 回答1: Few hints: Instead of converting the user input to float

问题 I need to do a user input validation, and I want it validated both in the client side and in the server side.

问题 I'm trying to make it so when the user clicks on a spot in my canvas, a popup is displayed that allows the user to enter two separate pieces of data. So I need two textblocks and then a way to save the data entered into some variables in the code behind. I've been looking at different tutorials and it's easy making a window with input texblocks. Just not sure how to do it with popups. The addNode_MouseDown method is where I tried adding the popup, since the information entered is going to be

问题 I need to do the following: Print "User please enter the age, sex, blah_blah" > $age>$sex>$blah_blah; print "the current user stats are- age = $age, sex = $sex"; my $rand; if ($blah_blah > $rand) { do something } else { something else } Can someone help me with to take inputs from the user and then be able to use that value in the script? I also want to be able to run this script as: perl script1 -age -sex -blah_blah By that I mean instead of asking the user to provide these values can I

问题 I have a personal project I've been working on. To work, it needs to accept a lot of data (relatively) from the user, in the form of four different kinds of data for 12 users. As such, I have quite a lengthy sequence of statements similar to this: cout << '\n' << "Monster A's name is: "; cin >> nameA; cout << '\n' << "Monster A rolled: "; cin >> rollM_A; cout << '\n' << "Monster A's Dex is: "; cin >> DexA; cout << '\n' << "Monster A's Mod is: "; cin >> ModA; cout << '\n' << "Monster A's Level

问题 I'm sorry if I duplicate, but I have tried EVERYTHING, and I can't figure out why this code keeps breaking. The highest-priority goal was to make this code handle input safely, or just anything that the user can type into the console, without it breaking. However, I also need it to be able to run more than once. fgets() won't let me do that since it keeps reading '\n' somewhere and preventing me from entering input more than once when it hits the end of the do/while loop. I have tried

问题 I want to test "real" typing of an user for my input element. To unit-test if my number.component in combination with my number-only.directive only accepts numeric inputs. The problem is the ngModel isn't updated on 'keydown' (KeyboardEvent), but is needed so the directive is triggered. The 'input' event requires to set the value of the nativeElement before dispatching it, which would skip the directive. I already experimented with fakeAsync, tick and whenStable, but didn't manage to recreate

问题 I have a user input that would be used in a search string that may contain a metacharacter For e.g. C# or C++ my grep command in a function was: grep -E "$1|$2" test.txt under direct replacement: grep -E "C\+\+|testWord" test.txt grep -E "C\#|testWord" test.txt the first caught the lines fine but not the second. Strangely, # was completely ignored. Without direct replacement, both catch anything with c followed by testWord instead of c++ and c# respectively I've tried handling it using sed
