  • Which is faster: in_array() or a bunch of expressions in PHP?

    - by Darryl Hein
    Is it faster to do the following: if ($var != 'test1' && $var != 'test2' && $var != 'test3' && $var != 'test4') { ... } Or: if (!in_array($var, array('test1', 'test2', 'test3', 'test4') { ... } Is there a number of values at which point it's faster to do one or the other? (In this case, the array used in the second option doesn't alreay exist.)

  • C++[MSVC2010]: How does switch compile and how optimized and fast is it?

    - by ekul
    As I found out that I can use only numerical values in C++'s switch statements, I thought that there then must be some deeper difference between it and a bunch of if-else's. Therefore I asked myself: (How) does switch differ from if-elseif-elseif in terms of runtime speed, compile time optimization and general compilation? I'm mainly speaking of MSVC here.

  • jquery: find common elements in 2 sets of divs

    - by tsiger
    For a markup like this: <div id="set1"> <div id="100">a div</div> <div id="101">another div</div> <div id="102">another div 2</div> <div id="120">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div> As you can see both #set1 and #set2 contain 2 divs with the same id (101, 120). Is it possible somehow with jQuery to find the common elements and add a class to the divs in #set1 that have the same id with divs in #set2? In other words after the script run the above code would look like this: <div id="set1"> <div id="100">a div</div> <div id="101" class="added">another div</div> <div id="102">another div 2</div> <div id="120" class="added">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div> EDIT playing around with it i did something but i am not sure it can go anywhere. I created an array with the ids in both sets and in Firebug i can see an array with the values var arrEl = []; $('#set1 div, #set2 div').each( function(index) { var id = $(this).attr('id'); arrEl.push(id); //maybe somehow check the array for the values that appear twice, and add the class to the //matching divs? });

  • Setting the value of textboxes with one of their attributes (jQuery)

    - by Jimbo
    I have a bunch of input text boxes that have the attribute ORIGINAL set to their initial value, so that when the user changes the textbox value, jQuery can highlight items that have changed (by comparing the text box's current value to the ORIGINAL attribute's value) What Im trying to do now is provide the user with a button that they can click to revert all text boxes back to their original values based on the value of the ORIGINAL attribute of each text box. Example $('input[type=text]').val($(this).attr('original')); The above doesnt work and I dont understand why.

  • Looking for a specific python gui module to perform the following task

    - by Sadaf Amouz
    I am looking for a GUI python module that is best suited for the following job: I am trying to plot a graph with many columns (perhaps hundreds), each column representing an individual. The user should be able to drag the columns around and drop them onto different columns to switch the two. Also, there are going to be additional dots drawn on the columns and by hovering over those dots, the user should see the values corresponding to those dots. What is the best way to approach this?

  • Listing C Constants/Macros

    - by ZJR
    Is there a way to make the GNU C Preprocessor, cpp (or some other tool) list all available macros and their values at a given point in a C file? I'm looking for system-specific macros while porting a program that's already unix savvy and loading a sparse bunch of unix system files. Just wondering if there's an easier way than going hunting for definitions.

  • Type casting int into double C++

    - by user1705380
    I am new to programming and this might be an obvious question, though i cannot for life of me figure out why my program is not returning as a double. I am suppose to write a stocks program that takes in shares of stock, whole dollar portion of price and the fraction portion. And the fraction portion is to be inputted as two int values, and include a function definition with 3 int values.The function returns the price as a double. #include <iostream> using namespace std; int price(int, int, int); int main() { int dollars, numerator, denominator, price1, shares; char ans; do { cout<<"Enter the stock price and the number of shares.\n"; cout<<"Enter the price and integers: Dollars, numerator, denominator\n"; cin>>dollars>>numerator>>denominator; cout<<"Enter the number of shares held\n"; cin>>shares; cout<<shares; price1 = price(dollars,numerator,denominator); cout<<" shares of stock with market price of "; cout<< dollars << " " << numerator<<'/'<<denominator<<endl; cout<<"have a value of " << shares * price1<<endl; cout<<"Enter either Y/y to continue"; cin>>ans; }while (ans == 'Y' || ans == 'y'); system("pause"); return 0; } int price(int dollars, int numerator, int denominator) { return dollars + numerator/static_cast<double>(denominator); }

  • Python 3.2: How to pass a dictionary into str.format()

    - by Robert Dailey
    I've been reading the Python 3.2 docs about string formatting but it hasn't really helped me with this particular problem. Here is what I'm trying to do: stats = { 'copied': 5, 'skipped': 14 } print( 'Copied: {copied}, Skipped: {skipped}'.format( stats ) ) The above code will not work because the format() call is not reading the dictionary values and using those in place of my format placeholders. How can I modify my code to work with my dictionary?

  • C++ STL list vs set

    - by mokaschitta
    Hi, what of those two is faster for random insertions and deletions? I guess list, having the values as the keys as it is with sets seems to be attractive too though. Is performance similar for iterating over the whole container? Thanks!

  • Can I use an "IN" filter on an Advantage Database Table (TAdsTable)?

    - by Anthony
    I want to apply a filter to an advantage table using multiple values for an Integer field. The equivalent SQL would be: SELECT * FROM TableName WHERE FieldName IN (1, 2, 3) Is it possible to do the same on an AdsTable within having to repeat the field using an "OR"? I want to something like: Filter := 'FieldName IN (1, 2, 3)' Instead of: Filter := 'FieldName = 1 OR FieldName = 2 OR FieldName = 3'

  • Replace for loop with formula

    I have this loop that runs in O(end - start) and I would like to replace it with something O(1). If "width" wouldn't be decreasing, it would be pretty simple. for (int i = start; i <= end; i++, width--) if (i % 3 > 0) // 1 or 2, but not 0 z += width; start, end and width have positive values
