Value of EOF under windows
问题 I wrote this code : #include <stdio.h> int main() { int c; while ((c = getchar()) != EOF) putchar(c); return 0; } Under windows, I figured out that I have to input ctrl+z so I can stop the program, I also printed the value of EOF and it's -1. However, when I enter -1 instead of ctrl+z the program continues to execute, and I want to understand why. Thank you! 回答1: Entering "-1" as text does not return the integer value -1 but two characters, i.e. a '-' (which corresponds to ASCII value 45 )
Node.js multiline input
问题 I'd like to prompt the user for input, let the user enter multiple lines of text, hitting enter between each line, then terminate the input by pressing CTRL+D or some such thing. With "keypress", I can catch the EOF, but I would have to handle all the echoing, backspace handling, terminal escape sequences, etc. manually. It would be much better if I could use "readline", but somehow intercept the CTRL+D (EOF) with "keypress", but I'm not sure how I would go about that. 回答1: You can use the
Go failing - expected 'package', found 'EOF'
问题 I've been having a hard time trying to execute a simple golang program in a virtual machine powered by vagrant. These are the relevant fields of my go env : GOARCH="amd64" GOPATH="/usr/local/src/go" GOROOT="/usr/local/go" GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64" This is the program I'm trying to execute ( located in /usr/local/src/go/program ): package program import ( "fmt" ) func main() { fmt.Print("Aloha") } This, the output that I get: main.go:4:5: /usr/local/go/src/fmt/doc.go:1:1:
feof和EOF的字符被重复读取问题的思考
void main() { PNode pNode; FILE *fp=fopen("1.txt","r"); pNode=Create(i); while(getc(fp)!=EOF) { int i; fscanf(fp,"%d",&i); pNode=Add(i,pNode); } fclose(fp); Print(pNode); } （问题源码如上所示） 问题介绍 我在温习C语言时，准备尝试编写单链表的结构，但是写到上面一段代码，运行后发现，文件的最后一个字符被重复读取了，焦头烂脑思考了一会儿，并且尝试搜集资料，写了这个博客。 问题思考 这个问题根源在文件读取上，因为我尝试了直接向链表中添加数据是没有任何问题的。而本程序使用了两个文件读取函数，即getc和fscanf，这两个函数的交错使用在一定程度上是程序结构有点混乱，这可能是我当时编程的时候没有用心思考造成的。 如果文件自身没有设置EOF的话，我们的getc函数遇到'\0'之后，将设置为EOF，再进入循环体一次，而fscanf已经读取不到有效字符了，因此返回EOF，但是此时i的值仍为最后一个整数的值，因此将再次读取该值。如果将下面一句 getc(fp)!=EOF 改为!feof(fp)，则问题仍会出现，原因同上。 代码解决之道 正确的做法应该是下面一段代码： PNode pNode; //从文件中读取数据并添加到链表中
IntelliJ IDEA: send EOF symbol to Java application
问题 When running a command-line Java application from IntelliJ IDEA, is it possible to send EOF symbol to the program awaiting input? In console this can be done using ctrl-d combination but in IDEA it doesn't work. 回答1: It's been implemented, use Ctrl+D / ⌘+D on Mac. https://www.jetbrains.com/idea/help/debug-tool-window-console.html 回答2: In Dec 2012, it was still not possible : http://devnet.jetbrains.com/thread/436131 来源： https://stackoverflow.com/questions/16484297/intellij-idea-send-eof
