It seems as if the reason you’re getting an error is because the userReadables is initially set to a null string. in the catch, you have catch(Exception e) { userReadables = null; } and since the userReadables is already null, it’s calling the Exception before it does anything else. Make it something related to the … Read more
To read the data $unsortedData = json_decode(file_get_contents(“data.json”), true); the second paramater true make you get an associative array, instead of getting an array of objects (stdclass) to sort the array: usort($unsortedData, function($a, $b){ return $a[‘serial’] < $b[‘serial’]; }); usort will sort the data according the callback passed as the second parameter, so you can customize … Read more
I’m not going to fix your code for you. Doing that is part of your homework. However, here are a couple of hints to start you in the right direction.

You could use the Object.keys() methods to iterate over your object and then use the Array.map() method to transform your object to the array structure you need. var data = { “0”: “value1”, “1”: “value2” } var newData = Object.keys(data).map(key => ({ [key]: data[key] })) console.log(newData) –Update– You would simply need to change the object … Read more
yes you can initialize an object without any parameters, let me explain simply, an object is just a copy from a class, it has a copy of all the public methods and fields inside this class. We use objects to access members of a class so let’s assume you have two classes X and Y … Read more
You have to change the get_name() to return a non-const reference, like string& get_name(); to get it working/compile. But will look strange. What you can do instead is pass the member name directly iss >> employee.name; that’s what friends do. And don’t forget to return the stream is. 1 solved Operator Overloading Error: no match … Read more
Introduction Operator overloading is a powerful feature of C++ that allows you to redefine the behavior of operators for user-defined types. However, when using operator overloading, you may encounter errors such as “no match for ‘operator>>’”. This error occurs when the compiler cannot find a suitable definition for the overloaded operator. In this article, we … Read more

I propose a solution for a input as an array of objects and an output as an object var data = [{question: “FirtName”, answer: “Daniel”}, {question: “LastNane”, answer: “Daniel2”}, {question: “Age”, answer: 80} ]; var result = {}; data.forEach(x => { result[x.question] = x.answer; }); console.log(result); 1 solved Combining nested objects [closed]
Let’s look at the code you’re trying to use: $http.get( ‘url’ ) .success(function(data) { var response = angular.fromJson(data); var mobilereceiver=”0147852369″; var messageId = response.ok.mobilereciever; }); You’re very close, in that you recognize that your string mobilereceiver holds the value that needs to be provided as the name of the final property. However, on your last … Read more
You could write a simple recursive function that will traverse the contents of your tree: var familyTree = { name: ‘Alex’, children: [ { name: ‘Ricky’, children: [ ] }, { name: ‘John’, children: [ { name: ‘Tom’, children: [ ] } ] } ] }; var traverse = function(tree) { console.log(tree.name); for (var i … Read more
