问题 Just for fun, I tried printing kbhit() with loops, so that the program after a key press prints the line infinitely until pressed keyboard again. It compiles well and when run, just gives blank screen. No prints. But upon single keypress ends the program. The console does not close though. #include <stdio.h> #include <conio.h> int main() { while(1) { if(kbhit()) { while(1) { if(kbhit()) { goto out; } printf("Print Ed Infinitum Until Key Press"); } } } out: return 0; } How do I solve this? 回答1

问题 My Dear All the Greatest Lords, It's most simple to install software packages in common use. But by means of such oversimplified routines lost control of varieties under different context of developing environments. After downloading, unzipping, plugging in the openblas2, I expect to enjoy the fortunate linear algebra computing functionality provided. Having succeeded in compiling a bunch of codes based on them, gcc broke off by encountering the following error, "cannot find -lgoto" Thanks in

问题 I am having a problem with the following script, which we wish to use as part of a login script in order to check if software has been installed, and if not, install it: :STEP1 for /f "delims= " %%a in (C:\software-dist.txt) do ( if "%%a"=="Softwarename1" goto STEP2 ) \\server\share\software1.exe echo Softwarename1 >> C:\software-dist.txt :STEP2 for /f "delims= " %%a in (C:\software-dist.txt) do ( if "%%a"=="Software name 2" goto END ) \\server\share\software2.exe /Q echo Software name 2 >> C

问题 This question already has answers here : Is there a goto statement in Java? (22 answers) Closed 5 years ago . I wrote a program in C++ with some goto statements. Now, I need to write the same program in Java. Is there any goto option in Java? If so, how it can be implemented? Is it same as the C++? My program is: #include<stdio.h> #include<conio.h> void main() { int i,j,k,w,l,q,d; clrscr(); printf("\nEnter the limit:"); scanf("%d",&k); for(i = 13; i <= k ; i++) { repeat: j = i%10; if (j != 0)

问题 I am coding for the NDS in c++ with libnds, but this question is not NDS-Specific. I currently have a text-based game in which the top screen just displays a logo, and you play on the bottom screen. So I want to add a type of single-DS multiplayer in which one player plays on the top screen, and the other on the bottom. I dont have a problem with setting up the text engine with both screens, I just need to find a method of efficiently coding in multiplayer. Below I wrote a summary or

问题 I usually fall into a situation where goto seems to be the best option to my mind. But I have read several times not to use it, and there is always an alternative. Now, I am trying something like this:- try{ //Something that requires internet connectivity; } catch{ //Show a message-Internet connectivity lost,and go back to try //-->FYI--Ignore "show message", because I am just appending this text to a // textbox. So there won't be a problem of multiple ShowMessage Boxes. } Now, the best

问题 I'm reading Perl which is quite interesting. But while reading goto from here in Perl I got a doubt. I know that goto statement has three types. goto LABEL. goto EXPR. goto &NAME. But in this three types, what is the use of third one goto &NAME ? This is also seems to be like a function call. Then, What is the real difference between goto &NAME and normal function call in Perl? When we use goto &NAME? Can anyone please explain with example. Thanks in advance. 回答1: It says in the goto page The

问题 I've heard rumors that PHP is planning on introducing a "goto" command. What is it supposed to be doing? I've tried searching a bit, but haven't found anything awfully descriptive. I understand that it won't be a " GOTO 10 "-like command... 回答1: They are not adding a real GOTO, but extending the BREAK keyword to use static labels. Basically, it will be enhancing the ability to break out of switch nested if statements. Here's the concept example I found: <?php for ($i = 0; $i < 9; $i++) { if
