user-input

问题 I am trying to go about creating a system for my users where they can select particular SCSS files they would like to be included in the project. They do this through a browser. Once they check off all the related SCSS files, they want to hit a browser based "compile" button to generate the final CSS. Is this possible? I have looked in the web for sometime but was unable to find anything. I know it's possible as I have seen it done for bootstrap, on their website. Would someone be able to let

问题 I am trying to write a C program that has to ask the user for input to take in 50 or less numbers. My problem is the "or less" numbers. How do I get the program to know when the user wants to stop entering numbers? 回答1: Here is the answer to your question:- #include <stdio.h> #include <stdlib.h> #include<conio.h> void main() { int a[100],n,i; printf("Enter the no of inputs u want to give (It must be less than or eqaual to 50)\n"); scanf("%d",&n); printf("Enter the nos \n"); if(n<=50) { for(i

问题 In my UWP app, I need to get information from the user to store in a database. In standard Windows this is easy, of course, by creating a modal dialog form and instantiating it when needed. But in UWP, although there are Dialogs, they seem limited to minimal and constrained functionality. What I want is something at least similar to a modal dialog form, where the user would enter information I could then use to insert into the database, but the closest thing I can see available in UWP is a

问题 I'm in an intro to C++ class and I was wondering of a better method of checking if input was the desired type. Is this a good way of doing this? I come from a PHP/PERL background which makes me rather apprehensive of using while loops. char type; while (true) { cout << "Were you admitted? [y/n]" << endl; cin >> type; if ((type == 'y') || (type == 'n')) { break; } } Is this a safe way of doing this or am I opening myself up to a world of hurt, which I suspect? What would be a better way of

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Div as modal - javascript Is there a way to somehow lock a page in Javascript until a function call is complete? What I have in mind is like a semi-transparent grey cover that prevents any other user actions such as mouse-overs or button clicks until the current request is done processing. The look-and-feel doesn't matter quite as much as the functionality, though. I haven't been able to find anything that does
