character

问题 If the maximum capacity of character is 256 how to store character array of 1000? is it possible to declare: char s[1000]; 回答1: Yes, it is certainly possible. char s[1000]; You can think of 1000 as the "length" of the array and 256 as the "width". You get an array of 1000 char s. Each char is 8 bits (on the machine you're using, at least), and can therefore store 256 distinct values. (And, actually, it would probably be more appropriate to think of the "width" as being 8, not 256.) Here is

问题 How to use character function of where the result is of unknown length initially? The trim() function, I understand, shows that it is possible not to specify the length of returning string. For example: write (*,*) trim(str) will return only part of the string without trailing spaces. This function does not have any idea about the length of returning string before the call. Or trim() function has limitations? On more variant is to find original code of trim() function. I have found (Returning

问题 I'm trying to loop through every character in a string . I only however know how to loop for every word in a string ussing the following: (set /P MYTEXT=)<C:\MYTEXTFILE.txt set MYEXAMPLE=%MYTEXT% for %%x in (%MYEXAMPLE%) do ( ECHO DO SOMTHING ) How can I configure it to work per character rather then per word? 回答1: AFAIK, FOR cannot do a character-wise iteration - A possible workaround is to build a loop like this: @ECHO OFF :: string terminator: chose something that won't show up in the

问题 I'm new to Codeigniter. Now I want to set the character limit in the view. First, get the data from the database with $query_result->result(), and then show it in the view using foreach(). Here is my Controller, Model and View: public function index() { $data = array(); $data['category'] = $this->product_model->selectAllcategory(); $data['randProduct'] = $this->product_model->selectRandomProduct(); $data['products'] = $this->product_model->selectAllProduct(); $data['maincontent'] = $this-

问题 Apparently there is a method that takes a char and returns a char: http://download.oracle.com/javase/6/docs/api/java/lang/Character.html#toLowerCase(char) But I can't seem to get it to work. My code: import java.lang.Character; public class Test { public static void main(String[] args) { char c = 'A'; c = toLowerCase(c); System.out.println(c); } } When I compile this, I get the following error: $ javac Test.java Test.java:6: cannot find symbol symbol : method toLowerCase(char) location: class

问题 I've been trying to learn sed and the examples I've found here are for swapping dates from 05082012 to 20120805 and I'm having trouble adapting them to my current need. I need to convert an IP address 10.4.13.22 to a reverse lookup of 22.13.4.10 for a nsupdate script. My biggest problem is the fact that sometimes each octet can change lengths e.g. 10.4.13.2 and 10.19.8.126 Thanks for any help! echo 10.0.2.99 | sed 's/\(....\)\(....\)/\2\1/' this is currently what I've tried, just based off

问题 Hi guys sorry for the noob question what are those \x1 ..\x2 ..\x3 characters and how to convert these to normal characters? 回答1: They are characters with the ordinal values 1, 2, and 3. They are called control characters and are not printable, which is why the debugger is showing you their escaped representation. You can look the control characters up in an ASCII table. 来源： https://stackoverflow.com/questions/17941513/how-to-convert-x1-x2-x3-characters-to-normal-characters-without-erasing-i

问题 I want to convert NSAttributedString containing RTFD to uppercase without losing attributes of existing characters and graphics. Thanks, 回答1: EDIT: @fluidsonic Is correct that the original code is incorrect. Below is an updated version in Swift, that replaces the text in each attribute range with an uppercased version of the string in that range. extension NSAttributedString { func uppercased() -> NSAttributedString { let result = NSMutableAttributedString(attributedString: self) result

问题 This should be a pretty simple regex question but I couldn't find any answers anywhere. How would one make a regex, which matches on either ONLY 2 characters, or at least 4 characters. Here is my current method of doing it (ignore the regex itself, that's besides the point): [A-Za-z0_9_]{2}|[A-Za-z0_9_]{4,} However, this method takes twice the time (and is approximately 0.3s slower for me on a 400 line file), so I was wondering if there was a better way to do it? 回答1: Optimize the beginning,

问题 I am trying to load in my data migration a member database. Quite a few of the names have special characters such as "Ciarán". I've set up a simple example like this: require 'rubygems' require 'fastercsv' FasterCSV.foreach("/Users/developer/Work/madmin/db/data/Members.csv") do |row| puts row.inspect end and I get the following: /usr/local/lib/ruby/gems/1.8/gems/fastercsv-1.5.0/lib/faster_csv.rb:1616:in `shift': FasterCSV::MalformedCSVError (FasterCSV::MalformedCSVError) when I hit the row
