I assume you mean this for the second using System; public class Test { private string x; public string GetX() { return x; } } In which case it is a method that returns a string while your first example is a readonly property solved Difference between get{return x} and return x [duplicate]

I’ll give you some hints, so as to not do your homework for you: !(a || b || c) = (!a && !b && !c) !(a && b && c) = (!a || !b || !c) !(a == b) = (a != b) !(a <= b) = (a > b) You should be able to … Read more
I will try to help you to get started: QList is std::list QStringList is basically QList < QString > , so it is the same std::fstream can be used for QFile QIODevice is maybe std::fstream, but I am not sure Again std::fstream can be used for QTextStream 3 solved How to convert Qt to C++? … Read more
Console.ReadLine gives you a string a string is, among other things, a collection of chars try this string number = “”; int numb = 0; Console.WriteLine(“Please enter the telephone number…”); number = Console.ReadLine(); for(int i=0; i<number.Count; i++) { if (number[i] == ‘A’) { //… } } solved Convert string to char error message [closed]
I believe what you are trying to do is to add a value to PizzaPrice, then display it on txtPizzaPrice.Text with the £ sign appended to the front. PizzaPrice should be a property rather than a field. public double PizzaPrice { get; set; } Notice that I += the value to pizza price, then display … Read more
My advise: A code at run time cannot be editted! Specially when you’re running the code and a client is using the service. You can edit the code by yourself only. Client would be using if else block statements only. You can edit the code, and add some if else blocks to it, so that … Read more
This is a generalized solution that works by these principles: Performs linear interpolation It calculates a “floating point index” into the input array This index is used to select 1 (if the fractional parts is very close to 0) or 2 numbers from the input array The integer part of this index is the base … Read more
In void add(cluster*), the name cluster resolves to the data member queue::cluser, not to the class name ::cluster. Avoid giving the same name to a type and to a variable. You are only confusing yourself. solved Cluster is not a type + cluster does not name a type error. Error for add(cluster *). Cant have … Read more
That should do it: #include <stdio.h> #define HEIGHT 5 #define WIDTH 7 int main() { int roof = WIDTH / 2; int offset = (WIDTH % 2 == 0) ? 1 : 0; for(int col_start = roof; col_start > 0; col_start–) { if(col_start != roof || offset != 1) { for(int col = 0; col … Read more
After an if and after an else there needs to be exactly one statement. The statement after if will be executed if the condition is true, the statement after else will be executed if the condition is false. Now the important thing to understand is the following: A single semicolon ; is a statement. It’s … Read more
This might be superfluous, I like using DispatcherTimer. This will tick every 2 seconds to look for a change: private DispatcherTimer _checkNumberTimer = null; private int _myNumber = int.MinValue; private int _lastValue = int.MaxValue; public Constructor1(){ _checkNumberTimer = new DispatcherTimer(); _checkNumberTimer.Tick += new System.EventHandler(HandleCheckNumberTick); _checkNumberTimer.Interval = new TimeSpan(0, 0, 0, 2); //Timespan of 2 seconds … Read more
The Best answer would be that List has some kind of Tracking over its list items and can update its items as you ask but a simple IEnumerable does not so it will not allow you to change them. solved Why can’t you modify a collection in a for each loop
Making a couple of guesses he is storing large amounts of data as arrays in his JavaScript for the site and trying to manipulate the DOM without a post back… Seems unlikely that this is being done without understanding AJAX / JSON, but I am guessing that is the answer he is looking for.

Well, Serial.println(“Resistance 1: ” + String(f1r) + ” ohms”); it uses the variable f1r whose scope just ended. In C++, when a variable is defined inside a scope (between some { and }), it does not exist outside of it. solved ‘ variable’ was not declared in this scope [closed]
