I have a class such as: class dialog { public: double dReturnType[][5][3]; }; #include <cstdlib> #include <iostream> include <string> using namespace std; #include "dialog.h"; int main(int argc, char *argv[]) { dialog People; People.dReturnType[0][1] = {1.2,2.3,6.6}; return 0; } It returns: [Warning] extended initializer lists only available with -std=c++11 or -std=gnu11 [enabled by default] [Error]: assigning to an array from an initializer list I've looked it up online a bit and really couldn't find a way to get around this. I'd prefer not editing the class within it's on class file (kinda

Suppose I have a struct array arr , where each element has a bunch of fields, including one called val . I'd like to increment each element's val field by some constant amount, like so: for i = 1:length(arr) arr(i).val = arr(i).val + 3; end This obviously works, but I feel there should be a way to do this in just one line of code (and no for loop). The best I've come up with is two lines and requires a temp variable: newVals = num2cell([arr.val] + 3); [arr.val] = deal(newVals{:}); Any ideas? Thanks. Just a note, the deal isn't necessary there: [arr.val] = newVals{:}; % achieves the same as

I'm trying to dynamically assign a controller for included template like so: <section ng-repeat="panel in panels"> <div ng-include="'path/to/file.html'" ng-controller="{{panel}}"></div> </section> But Angular complains that {{panel}} is undefined. I'm guessing that {{panel}} isn't defined yet (because I can echo out {{panel}} inside the template). I've seen plenty of examples of people setting ng-controller equal to a variable like so: ng-controller="template.ctrlr" . But, without creating a duplicate concurrant loop, I can't figure out how to have the value of {{panel}} available when ng

This has been bugging me for a while. struct person { char name[15]; int age; }; struct person me; me.name = "nikol"; when I compile I get this error: error: incompatible types when assigning to type ‘char[15]’ from type ‘char *’ am I missing something obvious here? Arrays are second-class citizens in C, they do not support assignment. char x[] = "This is initialization, not assignment, thus ok."; This does not work: x = "Compilation-error here, tried to assign to an array."; Use library-functions or manually copy every element for itself: #include <string.h> strcpy(x, "The library-solution to

Consider the following PHP Code: //Method 1 $array = array(1,2,3,4,5); foreach($array as $i=>$number){ $number++; $array[$i] = $number; } print_r($array); //Method 2 $array = array(1,2,3,4,5); foreach($array as &$number){ $number++; } print_r($array); Both methods accomplish the same task, one by assigning a reference and another by re-assigning based on key. I want to use good programming techniques in my work and I wonder which method is the better programming practice? Or is this one of those it doesn't really matter things? Since the highest scoring answer states that the second method is
