Scheme/Racket: most idiomatic way to append single element to end of list

阅读更多关于 Scheme/Racket: most idiomatic way to append single element to end of list

问题 I want to append the element b to the list a (let's say (a1, a2, ... an) ), e.g. appending the number 3 to (1 2) gives (1 2 3) So far I've been doing (append a (list b)) , which is kind of long and inelegant, so I wonder if there's a "better" way... 回答1: Are you building a list piecemeal, an item at a time? If so, the idiomatic way to do this is to build the list backward, using cons , and then reversing the final result: (define (map-using-cons-and-reverse f lst) (let loop ((result '())

So I'm having trouble understanding files in C++

阅读更多关于 So I'm having trouble understanding files in C++

问题 I just started learning files and I understand how to set it up and get it to work. I have to write this program where I have to allow the user to enter some information and have the user also update and adjust any data, using binary. So I can write up until the point where the user can write to and read from the file. But I don't know how to let the user adjust data or add data. #include <iostream> #include <fstream> #include <string> using namespace std; class client { public: string name;

Append div to body when URL hash # changes

阅读更多关于 Append div to body when URL hash # changes

问题 I'm using curtain.js and would like to keep a DIV (which holds navigation) visible at all times except for when the user is looking at the very first panel, i.e. at the top of the page. Currently the DIV resides within panel two I'm thinking perhaps of using the hash change as you scroll through the page to trigger an append to the body. Curtain.js creates an individual URL for each panel and the URL changes each time a panel is brought into view. I can append the div to the body (below) but

问题 I need to create lines like this: <li data-target="c1.html">I. Het tijdperk der goden</li> I really stumble with it, for example i can create <li> but when i try to add text to it then my span is gone. It's probably quite easy but i can't get it done. O yeah a lot of things can be done with a one-line solution. I don't care much about it being it compact, i prefer a clear solution (although one-line solutions can be clear). here the jsfiddle: http://jsfiddle

安装Git 最早Git是在Linux上开发的，很长一段时间内，Git也只能在Linux和Unix系统上跑。不过，慢慢地有人把它移植到了Windows上。现在，Git可以在Linux、Unix、Mac和Windows这几大平台上正常运行了。要使用Git，第一步当然是安装Git了。根据你当前使用的平台来阅读下面的文字：在Linux上安装Git 首先，你可以试着输入 git ，看看系统有没有安装Git： $ git The program 'git' is currently not installed. You can install it by typing: sudo apt-get install git 像上面的命令，有很多Linux会友好地告诉你Git没有安装，还会告诉你如何安装Git。如果你碰巧用Debian或Ubuntu Linux，通过一条 sudo apt-get install git 就可以直接完成Git的安装，非常简单。老一点的Debian或Ubuntu Linux，要把命令改为 sudo apt-get install git-core ，因为以前有个软件也叫GIT（GNU Interactive Tools），结果Git就只能叫 git-core 了。由于Git名气实在太大，后来就把GNU Interactive Tools改成 gnuit ，
