  • how does fgets internally works?

    - by Registered User
    Well it is a basic question but I seem confused enough. #include<stdio.h> int main() { char a[100]; printf("Enter a string\n"); scanf("%s",a); } Basically the above is what I want to achieve. If I enter a string James Bond then I want that to be stored in array a. But the problem is because of presence of a blank space in between only James word is stored. So how can I solve this one. UPDATE After the replies given below I understand fgets() would be a better choice. I want to know internal working of fgets as why is it able to store the string with space where as scanf is not able to do the same.

  • How Do I Pull Info from String

    - by Russ Bradberry
    I am trying to pull dynamics from a load that I run using bash. I have gotten to a point where I get the string I want, now from this I want to pull certain information that can vary. The string that gets returned is as follows: Records: 2910 Deleted: 0 Skipped: 0 Warnings: 0 Each of the number can and will vary in length, but the overall structure will remain the same. What I want to do is be able to get these numbers and load them into some bash variables ie: RECORDS=?? DELETED=?? SKIPPED=?? WARNING=?? In regex I would do it like this: Records: (\d*?) Deleted: (\d*?) Skipped (\d*?) Warnings (\d*?) and use the 4 groups in my variables.

  • Groovy GDK equivalent of Apache Commons StringUtils.capitalize(str) or Perl's ucfirst(str)

    - by knorv
    Yes/no-question: Is there a Groovy GDK function to capitalize the first character of a string? I'm looking for a Groovy equivalent of Perl's ucfirst(..) or Apache Commons StringUtils.capitalize(str) (the latter capitalizes the first letter of all words in the input string). I'm currently coding this by hand using .. str = str[0].toUpperCase() + str[1 .. str.size() - 1] .. which works, but I assume there is a more Groovy way to do it. I'd imagine ucfirst(..) being a more common operation than say center(..) which is a standard method in the Groovy GDK (see http://groovy.codehaus.org/groovy-jdk/java/lang/String.html).

  • ARM assembly puzzle

    - by ivant
    First of all, I'm not sure if solution even exists. I spent more than a couple of hours trying to come up with one, so beware. The problem: r1 contains an arbitrary integer, flags are not set according to its value. Set r0 to 1 if r1 is 0x80000000, to 0 otherwise, using only two instructions. It's easy to do that in 3 instructions (there are many ways), however doing it in 2 seems very hard, and may very well be impossible.

  • How do you tell if two wildcards overlap?

    - by Tom Ritter
    Given two strings with * wildcards, I would like to know if a string could be created that would match both. For example, these two are a simple case of overlap: Hello*World Hel* But so are all of these: *.csv reports*.csv reportsdump.csv Is there an algorithm published for doing this? Or perhaps a utility function in Windows or a library I might be able to call or copy?

  • Encoding a string as an integer .NET

    - by Paul Knopf
    I have a string that I would like represented uniquely as an integer. For example: A3FJEI = 34950140 How would I go about writing a EncodeAsInteger(string) method. I understand that the amount of characters in the string will make the integer increase greatly, forcing the value to become a long, not an int. Since I need the value to be an integer, I don't need the numerical representation to be entirely unique to the string. Maybe I can foreach through all the characters of the string and sum the numerical keycode of the character.

  • Run a function when a DOM element is created

    - by Ed Woodcock
    Hi folks, I want to bind an event to a certain class and ID for when matching objects are created in the DOM. I am doing this as I have some jQuery code in an ASP UpdatePanel, which causes the DOM to be re-loaded on its partial postback. I have reset the events with live(), however I need to call a 2 line initialisation function as soon as the elements are created. Is there any way to attach this to live(), or some other jQuery function, or will I have to write code to do this myself? Thanks, Ed

  • c# string.replace in foreach loop

    - by paradox
    Somehow I can't seem to get string replacement within a foreach loop in C# to work. My code is as follows : foreach (string s in names) { s.Replace("pdf", "txt"); } Am still quite new to LINQ so pardon me if this sounds amateurish ;)

  • JQuery - Fade in new Background Image?

    - by JasonS
    Hi, I think I may be trying something that isn't possible. I was recently tasked to create a html version of the flash site. On the flash site when you click on the body the image changes. I have done this with JQuery. Its brilliant! However.. it isn't "flash" enough. The powers that be want a fade effect between images. This is where I have come completely undone. This is how my script works at the moment. Images are stored in a div called photos. This is hidden. <div id="photos"> <img src="image.jpg" alt="Some caption" style="#page-bg-color" /> </div> When the page is loaded jquery checks to see if the first image is loaded. If it isn't then a loading symbol spins. When the image is loaded, it becomes the body background. $("body").css('background', 'url(' + photos[currentImage]["url"] + ') no-repeat 50% 50% fixed ' + photos[currentImage]["background"]); I have tried the following. I have tried animate. However, this doesn't work. I have tried this plugin: http://plugins.jquery.com/project/bgImageTransition This doesn't work either. It appears to clone the tag and do something. I assume it isn't working because you cannot clone the body tag. That or it is really old and is no longer compatible with the current version of JQuery. I fear that I have coded my way down a dead end. Does anybody know how I could make this work?

  • Extracting URLs (to array) in Ruby

    - by FearMediocrity
    Good afternoon, I'm learning about using RegEx's in Ruby, and have hit a point where I need some assistance. I am trying to extract 0 to many URLs from a string. This is the code I'm using: sStrings = ["hello world: http://www.google.com", "There is only one url in this string http://yahoo.com . Did you get that?", "The first URL in this string is http://www.bing.com and the second is http://digg.com","This one is more complicated http://is.gd/12345 http://is.gd/4567?q=1", "This string contains no urls"] sStrings.each do |s| x = s.scan(/((http|https):\/\/[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(([0-9]{1,5})?\/.[\w-]*)?)/ix) x.each do |url| puts url end end This is what is returned: http://www.google.com http .google nil nil http://yahoo.com http nil nil nil http://www.bing.com http .bing nil nil http://digg.com http nil nil nil http://is.gd/12345 http nil /12345 nil http://is.gd/4567 http nil /4567 nil What is the best way to extract only the full URLs and not the parts of the RegEx? Thanks Jim

  • Image upload - Latin chars problem

    Dear Gods! I use this script to upload images to serveR: <?php if (($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg" && ($_FILES["image_upload_box"]["size"] < 2000000)) { $max_upload_width = 450; $max_upload_height = 450; if(isset($_REQUEST['max_width_box']) and $_REQUEST['max_width_box']!='' and $_REQUEST['max_width_box']<=$max_upload_width){ $max_upload_width = $_REQUEST['max_width_box']; } if(isset($_REQUEST['max_height_box']) and $_REQUEST['max_height_box']!='' and $_REQUEST['max_height_box']<=$max_upload_height){ $max_upload_height = $_REQUEST['max_height_box']; } if($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg"){ $image_source = imagecreatefromjpeg($_FILES["image_upload_box"]["tmp_name"]); } $remote_file =$directory."/".$_FILES["image_upload_box"]["name"]; imagejpeg($image_source,$remote_file,100); chmod($remote_file,0644); list($image_width, $image_height) = getimagesize($remote_file); if($image_width>$max_upload_width || $image_height >$max_upload_height){ $proportions = $image_width/$image_height; if($image_width>$image_height){ $new_width = $max_upload_width; $new_height = round($max_upload_width/$proportions); } else{ $new_height = $max_upload_height; $new_width = round($max_upload_height*$proportions); } $new_image = imagecreatetruecolor($new_width , $new_height); $image_source = imagecreatefromjpeg($remote_file); imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height); imagejpeg($new_image,$remote_file,100); imagedestroy($new_image); } imagedestroy($image_source); }else{ something.... } ?> This is works well, till i upload a photo with latin chars in filename. For example the filename: kék hegyek.jpg. After upload file name will be: KA©k hegyek.jpg How can i solve this? Thank you

  • Remove first and last characters from a string in Lisp

    - by powerj1984
    I am passing in command line arguments to my Lisp program and they are formatted like this when they hit my main function: ("1 1 1" "dot" "2 2 2") I have a dot function and would like to call it directly from the argument, but first I must strip the " characters. I tried variations of this function: (defun remove-quotes (s) (setf (aref s 0) '"")) to no avail, Lisp complains that "" is not a member of base-char. Thanks!

  • How can I make nested string splits?

    - by Statement
    I have what seemed at first to be a trivial problem but turned out to become something I can't figure out how to easily solve. I need to be able to store lists of items in a string. Then those items in turn can be a list, or some other value that may contain my separator character. I have two different methods that unpack the two different cases but I realized I need to encode the contained value from any separator characters used with string.Split. To illustrate the problem: string[] nested = { "mary;john;carl", "dog;cat;fish", "plainValue" } string list = string.Join(";", nested); string[] unnested = list.Split(';'); // EEK! returns 7 items, expected 3! This would produce a list "mary;john;carl;dog;cat;fish;plainValue", a value I can't split to get the three original nested strings from. Indeed, instead of the three original strings, I'd get 7 strings on split and this approach thus doesn't work at all. What I want is to allow the values in my string to be encoded so I can unpack/split the contents just the way before I packed/join them. I assume I might need to go away from string.Split and string.Join and that is perfectly fine. I might just have overlooked some useful class or method. How can I allow any string values to be packed / unpacked into lists? I prefer neat, simple solutions over bulky if possible. For the curious mind, I am making extensions for PlayerPrefs in Unity3D, and I can only work with ints, floats and strings. Thus I chose strings to be my data carrier. This is why I am making this nested list of strings.
