An integer is a single number with no decimal part, e.g., 3, 28, -76, 154, etc. You have a string, “0/5”. “0/5” doesn’t represent a number (especially as you’ve said it’s not a fraction), so it can’t be converted to an integer because it’s not the same kind of data. You’ll need to change the … Read more
Func f();, it prints nothing, it should print Constructor That is not true whatsoever. Here is how you create a Func: Func f; When I try to use operator() f(2) it gives me compilation error. error C2660: ‘f’ : function does not take 1 arguments. Isn’t it strange behaviour or I am missing something? Yes, … Read more
As the compiler is telling you, this line: Note n = Note(&track.generator); Tries to construct a Note and supply a Generator** to its constructor (since track.generator has type Generator*, &track.generator has type Generator**). However, your Note class constructor accepts a Generator*, not a Generator**. Just do this instead (notice, that copy-initialization is unnecessary here, rather … Read more
using System; class Program { static void Main(string[] args) { string[] cijfers = new string[10] { “7”, “8”, “4”, “6”, “5.5”, “7.5”, “2”, “3.3”, “4.9”, “8.9” }; int i = 0; double sum=0; for (i = 0; i < 10; i++) { sum+=double.Parse(cijfers[i]); Console.WriteLine(“The sum is: {0}”,sum); } Console.Write(“The average is: {0}”,sum/10); } } solved … Read more
If I understand your question correctly, you want to use that SuperAwesomeNinjaMethod with the indicated signature, and for the second argument, you want to pass an instance of System.Collections.Generic.Dictionary<TKey, TValue>, right? The Dictionary class implements the ICollection interface, hence you can just pass your Dictionary instance. You will get a collection of KeyValuePair<TKey, TValue> solved … Read more

To be able to await MyTimeConsumingTask it must be declared to return a Task. public async Task<SimeType> MyTimeConsumingTask() Since you said it does some network IO, you can rewrite it using async NW IO methods and then await it as var MyResult = await MyTimeConsumingTask(MyClassProperty); But in your case the simplest approach seems to be … Read more
Just looking at their codeplex page it seems it supports Apache Cassandra 0.6.2 or above. 1 solved Which version of Cassandra does Aquiles v0.7.0.6 support? [closed]
The speed difference is largely due to the iostream I/O functions maintaining synchronization with the C I/O functions. We can turn this off with a call to std::ios::sync_with_stdio(false); By default standard C++ streams are synchronized to the standard C stream after each input/output operation. Once synchronization is turned off, the C++ standard streams are allowed … Read more
You could use the SmtpClient class to send email in .NET: using (var client = new SmtpClient(“127.0.0.1”, 25)) using (var message = new MailMessage(“[email protected]”, “[email protected]”)) { message.Subject = “some subject”; message.Body = “test body”; client.Send(message); } 1 solved convert vb email send code to c# [closed]
I totally agree with the other answers and comments, but for convenience here is the code public class Program { public static void Main() { Console.WriteLine(“Who is the best?”); var answer = Console.ReadLine(); if (answer.Equals(“tim”)){ Console.WriteLine(“You’re right!”) } else { Console.WriteLine(“Wrong!”) } } } 1 solved C# How to have it read words and output … Read more
Your logic is confused, you’re trying to do too much at once. Separate out the different things you are trying to do. Like this void generator(){ // set the whole area to “+” for(int rows=0; rows<10; rows++) for(int cols=0; cols<10;cols++) gameArea[rows][cols] = “+”; // set the position of the hero gameArea[x][y] = hero; // print … Read more
I made several changes to your code. I removed guard headers since we use it only in header files. Old-fasioned memset has been replaced by operation on strings. I suspect that you need to pass char* to CCRC32 object hence sSourceFile is still const char*. I compiled code except parts with CCRC32. #include <iostream> #include … Read more

Take a look at the BitCoin documentation. vRecv is an instance of CDataStream which overloads the operator>> to read and unserialize data. Background To understand the expression, precedence and associativity of operators are important. In C++, the >> operator is left-associative, which means you can rewrite your expression (vRecv >> locator) >> hashStop; // Or … Read more
