  • Input/ Output alternatives for printf/scanf

    - by Nitish
    It may sound strange that knowing a lot about ios and haing some experience in .net, I am a newcomer to C. Somewhere I got this target to find average of n numbers without using printf and scanf. I don't want the code for the program but it will be really helpful if someone can help me with the alternatives to the mentioned functions. Please let me know if code with printf/scanf is required here. Also do let me know if my query stands invalid. Thanks and Regards, Nitish

  • Javascript: Select option based on its contents

    - by Zac Altman
    Basically this, but in pure javascript: http://stackoverflow.com/questions/2346257/how-to-get-value-of-select-tag-based-on-content-of-select-tag-using-nokogiri So I have a select list with a lot of countries/states, and I want to be able to select one based on what is between the tags. Argentina (I know i could use the value, but each one is a random mesh of numbers, so i would have to collect each individual one - not economical...)

  • How to access static members in a Velocity template?

    - by matt b
    I'm not sure if there is a way to do this in Velocity or not: I have a User POJO which a property named Status, which looks like an enum (but it is not, since I am stuck on Java 1.4), the definition looks something like this: public class User { // default status to User private Status status = Status.USER; public void setStatus(Status status) { this.status = status; } public Status getStatus() { return status; } And Status is a static inner class: public static final class Status { private String statusString; private Status(String statusString) { this.statusString = statusString; } public final static Status USER = new Status("user"); public final static Status ADMIN = new Status("admin"); public final static Status STATUS_X = new Status("blah"); //.equals() and .hashCode() implemented as well } With this pattern, a user status can easily be tested in a conditional such as if(User.Status.ADMIN.equals(user.getStatus())) ... ... without having to reference any constants for the status ID, any magic numbers, etc. However, I can't figure out how to test these conditionals in my Velocity template with VTL. I'd like to just print a simple string based upon the user's status, such as: Welcome <b>${user.name}</b>! <br/> <br/> #if($user.status == com.company.blah.User.Status.USER) You are a regular user #elseif($user.status == com.company.blah.User.Status.ADMIN) You are an administrator #etc... #end But this throws an Exception that looks like org.apache.velocity.exception.ParseErrorException: Encountered "User" at webpages/include/dashboard.inc[line 10, column 21] Was expecting one of: "[" ... From the VTL User Guide, there is no mention of accessing a Java class/static member directly in VTL, it appears that the right hand side (RHS) of a conditional can only be a number literal, string literal, property reference, or method reference. So is there any way that I can access static Java properties/references in a Velocity template? I'm aware that as a workaround, I could embed the status ID or some other identifier as a reference in my controller (this is a web MVC application using Velocity as the View technology), but I strongly do not want to embed any magic numbers or constants in the view layer.

  • Mathematica equivalent of Ruby's inject

    - by Ben Alpert
    Is there a Mathematica function like inject in Ruby? For example, if I want the product of the elements in a list, in Ruby I can write: list.inject(1) { |prod,el| prod * el } I found I can just use Product in Mathematica: Apply[Product, list] However, this isn't general enough for me (like, if I don't just want the product or sum of the numbers). What's the closest equivalent to inject?

  • Possible to download entire whois database / list of registered domains?

    - by Parand
    I wanted to do some analysis on registered domain names. Looks like I can hit whois.internic.net to get information about each domain, but it also looks like there are rate limits that prevent me from doing large numbers of queries. Is there a way to periodically (say daily) grab the entire whois database? I really only care about whether a domain is registered or not, so I don't need the full whois information.

  • Setting wildcard queries as default for QueryParser

    - by user46703
    When my users enter a term like "word" I would like it be treated as a wildcard query "word*" so all terms beginning "word" are found. Is there a way to tell the QueryParser to automatically create wildcard queries or do I have to parse the query myself? This shouldn't be a problem for simple queries but it may become tricky for more complex queries.

  • Validate a number between 10 and 11 characters in length

    - by Montana Flynn
    I am using javascript (and PHP) to validate a simple form with a phone number field. I have it working fine checking that the field has only 10 characters, but I really want to check if the field has between 10 and 11 characters. Reason being, some people type numbers like so: 1 555 555 5555 and some people do this 555 555 5555. Here is what I have that works for checking if the length is 10: if (!(stripped.length == 10)) { alert("Please enter a valid US phone number.") return false }

  • How to store an array as the value in Tokyo Cabinet?

    - by punkish
    Is there any way I can store an array of numbers in a Tokyo Cabinet db? For example, I have predictable arrays of values such as 1 => [1, 2, 444, 0.987], 2 => [2, 23, 123, -0.234], 3 => [3, 1, 34, 1.456] I would like to store the above in a TC fixed length db. Is there a way to store the above as arrays instead of as strings?

  • Learning to write organized and modular programs

    - by Peter
    I'm a computer science student, and I'm just starting to write relatively larger programs for my coursework (between 750 - 1500 lines). Up until now, it's been possible to get by with any reasonable level of modularization and object oriented design. However, now that I'm writing more complex code for my assignments I'd like to learn to write better code. Can anyone point me in the direction of some resources for learning about what sort of things to look for when designing your program's architecture so that you can make it as modularized as possible?

  • Can you set SQL Server permissions from a Silverlight app?

    - by Paul Smith
    Is it possible to create a Silverlight application which can be used to provide a nice user interface for managing SQL Server permissions? We want to create a simple admin app to allow certain users to create new users, disable old users, and manage specific permissions for those users, but we feel that SQL Server Management Studio is perhaps too complex.

  • Overload operator in F#

    - by forki23
    Hi, I would like to overload the (/) operator in F# for strings and preserve the meaning for numbers. /// Combines to path strings let (/) path1 path2 = Path.Combine(path1,path2) let x = 3 / 4 // doesn't compile If I try the following I get "Warning 29 Extension members cannot provide operator overloads. Consider defining the operator as part of the type definition instead." /// Combines to path strings type System.String with static member (/) (path1,path2) = Path.Combine(path1,path2) Any ideas? Regards, forki

    - by pyrony
    I am having a hard time figuring out a reasonable way to generate a mixed-case hash in Python. I want to generate something like: aZeEe9E Right now I'm using MD5, which doesn't generate case-sensitive hashes. What is a good way to generate a hash value consisting of upper- and lower- case characters + numbers?

  • Is there a pretty print for PHP?

    - by Aaron Lee
    I'm fixing some PHP scripts and I'm missing ruby's pretty printer. i.e. require 'pp' arr = {:one => 1} pp arr will output {:one = 1}. This even works with fairly complex objects and makes digging into an unknown script much easier. Is there some way to duplicate this functionality in PHP?

  • Debugging php-cli scripts with xdebug and netbeans?

    - by wurdalack
    I have managed to initiate php-cli script debug session from the IDE itself, but I need to start the debugging session from the shell / command line. These are rather complex maintenance PHP scripts which take a lot of input parameters, so entering arguments from within Netbeans is a bit cumbersome. I have done it before with Zend studio http://kb.zend.com/index.php?View=entry&EntryID=130 but now I need to get it working with Netbeans. Thanks in advance.

  • BigInteger.pow(BigInteger) ?

    - by PeterW
    I'm playing with numbers in Java, and want to see how big a number I can make. It is my understanding that BigInteger can hold a number of infinite size, so long as my computer has enough Memory to hold such a number, correct? My problem is that BigInteger.pow accepts only an int, not another BigInteger, which means I can only use a number up to 2,147,483,647 as the exponent. Is it possible to use the BigInteger class as such? BigInteger.pow(BigInteger) Thanks.

  • Best way to enter numeric values with decimal points?

    - by Andrew Grant
    In my app users need to be able to enter numeric values with decimal places. The iPhone doesn't provides a keyboard that's specific for this purpose - only a number pad and a keyboard with numbers and symbols. Is there an easy way to use the latter and prevent any non-numeric input from being entered without having to regex the final result? Thanks!

  • PHP 5.2 Function needed for GENERIC sorting of a recordset array

    - by donbriggs
    Somebody must have come up with a solution for this by now. We are using PHP 5.2. (Don't ask me why.) I wrote a PHP class to display a recordset as an HTML table/datagrid, and I wish to expand it so that we can sort the datagrid by whichever column the user selects. In the below example data, we may need to sort the recordset array by Name, Shirt, Assign, or Age fields. I will take care of the display part, I just need help with sorting the data array. As usual, I query a database to get a result, iterate throught he result, and put the records into an assciateiave array. So, we end up with an array of arrays. (See below.) I need to be able to sort by any column in the dataset. However, I will not know the column names at design time, nor will I know if the colums will be string or numeric values. I have seen a ton of solutions to this, but I have not seen a GOOD and GENERIC solution Can somebody please suggest a way that I can sort the recordset array that is GENERIC, and will work on any recordset? Again, I will not know the fields names or datatypes at design time. The array presented below is ONLY an example. UPDATE: Yes, I would love to have the database do the sorting, but that is just not going to happen. The queries that we are running are very complex. (I am not really querying a table of Star Trek characters.) They include joins, limits, and complex WHERE clauses. Writing a function to pick apart the SQL statement to add an ORDER BY is really not an option. Besides, sometimes we already have the array that is a result of the query, rather than the ability to run a new query. Array ( [0] => Array ( [name] => Kirk [shrit] => Gold [assign] => Bridge ) [1] => Array ( [name] => Spock [shrit] => Blue [assign] => Bridge ) [2] => Array ( [name] => Uhura [shrit] => Red [assign] => Bridge ) [3] => Array ( [name] => Scotty [shrit] => Red [assign] => Engineering ) [4] => Array ( [name] => McCoy [shrit] => Blue [assign] => Sick Bay ) )
