问题 i would have to show the table of reservation of 3 biens it should show me 3 line of 3 reservation but it show me just one line in the controllers public function index_hote() { $this->Reservation->recursive = 1; $this->loadModel("BiensPersonne"); if($this->Session->read('Auth.User.0.Personne.id')){ $options = $this->BiensPersonne->findByPersonneId($this->Session- >read('Auth.User.0.Personne.id')); $this->loadModel("Personne"); $biens=$this->Personne->findById( $options['BiensPersonne'][

问题 My code looks like this: someArray.forEach(x => { // do something console.log(‘calling api for ‘ + x); callAnHttpApiAsync(...); sleep(10); }); The http api call is async (but I don’t use any await/async syntax) and logs something once the api sends back the response. What happens is that the forEach loop is completed and I start to see the logged responses ONLY AFTER that. I’d expect to see some responses before the loop is over (I tried increasing the amount of sleep), but no matter how long

问题 In my the cs106b book we use the expression "foreach" to go through a list of words in a Map. I implemented the code and banged my head against the wall facing mysterious errors. Here's the code: void DisplayWordCounts(Map<int> & wordsCount) { foreach (string word in wordsCount) { cout << left << setw(15) << word << right << setw(5) << wordsCount[word] << endl; } } on the line starting with "foreach" I get the following errors: lesson4-macbeth/life.cpp:58: error: expected primary-expression

问题 This is the first time that I've seen this kind of syntax : // class Node public class Node { ... ... } public class Otherclass { ... } Otherclass graph = new Otherclass(); // getSuccessors is a method of Otherclass class Node currentNode ; List<Node> successors = graph.getSuccessors(currentNode); // weird for loop for (Node son : successors) { // do something } What is that for loop ? some kind of a Matlab syntax ? Is there any other way to write that for loop ? Regards 回答1: It's a for each

问题 I have a sample code which creates an "array" of size 10 and tries to initialize it with reverse values in a For loop e.g:(9,8,7,6,5...0): int[] array = new int[10]; for (int i = array.length - 1, j = 0; i >= 0; i--, j++) { System.out.println("Present value of i=" + i + " Present value of j=" + j); array[j] = i; System.out.println("Array:" + j + "=" + i); } for (int k : array) { System.out.println(array[k]); } So far so good. This is the output from console which is perfect: Present value of

问题 is there a way I can use a PHP loop to create a list like the following with the previous 12 months, based on the current month (excluding the current month) ? The value should always be the first of the month (format: yyyy-mm-dd) and the dropdown itself should just show year and month (format: yyyy-mm): <option value="2014-03-01">2014-03</option> <option value="2014-02-01">2014-02</option> <option value="2014-01-01">2014-01</option> <option value="2013-12-01">2013-12</option> <option value=

问题 This question already has answers here : Does Class need to implement IEnumerable to use Foreach (11 answers) Closed 6 years ago . I was wondering, when exactly can I use the foreach loop? Do I have to implement IEnumerable? 回答1: There is no need to implement the IEnumerable interface to use the foreach statement. Here is a quote from the MSDN (http://msdn.microsoft.com/en-us/library/9yb8xew9.aspx): In C#, it is not absolutely necessary for a collection class to inherit from IEnumerable and

问题 So I've been getting into the new C++ using GCC 4.6 which now has range-based for-loops. I've found this really nice for iterating over arrays and vectors. For mainly aesthetic reasons I wondered if there was a way to use this to replace the standard for(int i = min; i < max; i++) {} with something like for(int& i : std::range(min, max)) {} Is there something natively built into the new C++ standard that allows me to do this? Or do I have to write my own range/iterator class? 回答1: I don't see

问题 I have a matrix of n variables and I want to make an new matrix that is a pairwise difference of each vector, but not of itself. Here is an example of the data.
