This is C++17 syntax. As this standard is not yet the default option for most compilers you have to tell the compiler that you are using it via the -std=c++17 switch. PS: you didn’t say which compiler you are using, so maybe it will not support that switch or not even support C++17 at all. … Read more

IMO, best will be to use a Dictionary<string,int[][]>. During creation you will place a new array (which you just created) and assosiate it to the key “a” + i. To get this array, just get the value attached to the relevant key. Something like (C#-like pseudo code): var map = new Dictionary<string,int[][]>(); for(int i=1;i<10;i++) { … Read more
Hi here i am using this to import from Excel File.Try this.Works 100%… Here you should have a folder inside your application named as “Files” where after uploading your excel file,it will be stored and your program will read from the excel file available inside “Files” Folder. protected void btnImport_Click(object sender, EventArgs e) { ArrayList … Read more
From personal experience: You would generally have Private data member when you do not want it to be accessed externally through another class that calls the class containing the Private data member. Public data members are those that you can access by other classes to obtain its contents. My opinion is that it is simply … Read more
Just do int i,j; std::string line; while(std::getline(cin,line) && !line.empty()){ std::istringstream iss(line); if(iss >>i>>j) { //LOOP BODY } } 2 solved how to check if int input is empty or user pushed enter key in a while loop C++
if an employee’s datas changed in HR database automatically FD system must notified to refresh his database Consider looking at SQL Server Replication (or) AlwaysOn feature for this same purpose. Specifically you should look at Transactional Replication 2 solved C# Webservice to copy datas from one DB to Another [closed]
Lets make it very simple. Create a Process field and use it everywhere: private Process pNotepad; //Process field void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) { if (e.Result.Text == “alice present”) { SoundPlayer sndPlayer = new SoundPlayer(Ai.Properties.Resources.My_name_is_A_L_I_C_E); sndPlayer.Play(); } if (e.Result.Text == “open notepad”) { //starting Process “notepad” pNotepad = new Process(); pNotepad.StartInfo.FileName = “notepad.exe”; pNotepad.Start(); } … Read more
This should fix your problem. It will parse all rows and place each line in a string stream. It then parses the string stream and streams the elements into doubles. It should work for any combination of rows and column elements. #include <iostream> #include <fstream> #include <string> #include <sstream> #include <vector> using namespace std; int … Read more
You can use std::fstream: #include <fstream> #include <iostream> int myint; int main() { // when entering app: std::ifstream fs(“data.txt”); if ( fs ) { fs >> myint; } fs.close(); std::cout << myint; myint++; // when exiting app: std::ofstream fs2(“data.txt”); fs2 << myint; } 2 solved How can I store a variable in another file?
The value of y will be 2. Here’s how I got it to work in Visual Studio: #include “stdafx.h” #include <iostream> class car { public: static int x; car(); }; int car::x = 0; car::car(){ x = x + 1; } int main() { car first = car();// here the value of x is 1; … Read more

It’s very unclear what you want to do because on the one hand you mention you want to use Substring and IndexOf, and on the other hand, you put it on comment and say you want to check if it’s null, and which you’re already checking if the string customFolders is null or empty. I … Read more
as a simple fix here is the code if (j.Equals(leguess))// If the character = the letter guess { int index = word.IndexOf(j);// Get the index of j while (index > -1) { guess = guess.Remove(index, 1).Insert(index, j.ToString()); index = word.IndexOf(j, index + 1); } } I have inserted a while loop to replace all the … Read more
