[ad_1] The empty statement returns nothing at all (empty: “no value of any type”). A statement list, like the one in the body of a Script that eval is parsing the code as, returns the value of the last statement that did return anything: The value of a StatementList is the value of the last … Read more
[ad_1] Let me explain what foreach actually does. It iterates over a collection of elements inside an IEnumerable, in order, without skipping anything, even if the current element has the value null. If you have an array with [5,2,24], the elements will be called in oder 5, 2, 24 and will stop after that. 5 … Read more
[ad_1] You might have posted partial code, according to your comments your controller should be like below. DEMO var demoapp = angular.module(“myApp”,[]); demoapp.controller(“ulCtrl”,function($scope){ $scope.customers = “CUSTOMERSSS” ; }); <!doctype html> <html ng-app=”myApp”> <head> <script src=”https://ajax.googleapis.com/ajax/libs/angularjs/1.4.4/angular.js”></script> </head> <body> <div ng-controller=”ulCtrl” style=”padding: 40px;”> <li ng-controller=”ulCtrl”><a ng- href=”” class =”active” >{{customers}}</a></li> <li><a ng-href=”#JOBS”>JOBS</a></li> <li><a ng-href=”#ESTIMATES” >ESTIMATES</a></li> <li><a ng-href=”#INVOICE” … Read more
[ad_1] Try like this: #include <string> #include <iostream> class Pulley{ private: int noOfTeeth; public: Pulley(int teeth = 0); void show(); }; Pulley::Pulley(int teeth) : noOfTeeth(teeth) { std::cout << “Pulley constructor called!”; } void Pulley::show() { std::cout << “\n\nNo of Teeths of Pulley: ” << noOfTeeth; } class GearBox{ private: std::string transmission; Pulley p; public: GearBox(std::string … Read more
[ad_1] One example would be errors when they are encountered. e.g. in validation errors[:base] << “Value must be an integer.” [ad_2] solved When should you use an empty array in a web application? [closed]
[ad_1] You can create a browser extension which logs each request made from the browser. You can then post that data, for example as a .har file, to a server. Without using an extension you can use PerformanceObserver to observer all requests made from the document, send each entry as JSON to server. [ad_2] solved … Read more
[ad_1] It depends on how your class looks but this would be a simple example: #include <iostream> using namespace std; class MyClass { int x; public: void setX(int i) { x = i; } int getX() { return x; } }; int main() { MyClass test[4]; int i; for(i=0; i < 4; i++) test[i].setX(i); ` … Read more
[ad_1] You just need to use an if..else statement: function RandomID() { var value; var rnd = Math.floor(Math.random() * 11); if (rnd === 7) value = “Wassup”; else if (rnd <= 5) value = “Hello”; else value = rnd; document.getElementById(‘id’).value = value; } <button class=”button” onclick=”RandomID();” style=”font-family: sans-serif;”>RUN</button> <input class=”input” type=”text” id=”id” name=”id” size=”3″ readonly … Read more
[ad_1] The file stdout, which is what printf writes to, is by default line buffered. That means everything you write to it is buffered, i.e. stored in memory, and is flushed (and actually printed) when you print a newline. 2 [ad_2] solved C char array storing a variable [closed]
[ad_1] Buff_Y[2] = (Y / 100) + 0x30; Buff_Y[1] = (Y / 10) % 10+0x30; Buff_Y[0] = (Y % 10) + 0x30; This is all good. If you print those three bytes, you will see that they contain the right values. SBUF = *Buff_Y; This, however, indicates confusion. *Buff_Y is equivalent to Buff_Y[0]. That is … Read more
[ad_1] You could use the length of the string as the determinant of whether to format the string using ‘p’ or ‘£’, then use .substring() to get the individual parts of the string (the euros and cents) Here’s an example: if(string.length() < 3) { System.out.println(string+”p”); } else { System.out.println(“£”+string.substring(0, string.length()-2)+”.”+string.substring(string.length-2)); } What this does is: … Read more
[ad_1] I was close to closing this question as you didn’t include your workings. But I’ve seen your comment – you should edit your question to include that. So here’s your code: use POSIX ‘strftime’; print strftime “%Y_%m_%d_%H_%M_%S/n”, localtime() – 24 * 60 * 60); That’s pretty close. You have three small issues. You have … Read more
[ad_1] You had the right idea with int e = 0 in your earlier comment. for (int i=0; i<towns.length; i++){ if(!towns[i].contains(“p”)){ int e=0; for (int j=0; j<towns[i].length; j++){ if(towns[i].charAt(j) == ‘e’ || towns[i].charAt(j) == ‘E’){ e++; } } if(e>1 && e<5){//This is assuming you don’t want to print cities with more than 4 E’s System.out.println(towns[i]); … Read more
[ad_1] If you are puzzled about the dots here is what they are: %.1lf is the format specification for precision. This is requesting one digit after the decimal point in the printf output. The 1. and 2. in (a*1.+b)/2. mean that those literals are double (as opposed to 1 that would be int and 1.f … Read more
[ad_1] Either use single quotes, like q = “select tbuc.csId, tbuc.uId, tbuc.cId, tbui.role_type, tbuc.time as login_date” + “, tbuc.sessId, (case when tbui.role_type=”ROLE_USER” then 1 else 0 end) ” + “as assignment_submitted FROM tb_user_click tbuc, tb_user_info tbui WHERE ” + “tbui.user_id = tbuc.uId and tbuc.csId = tbui.class_section_id;” Or escape the double quotes, like q = “select … Read more
