First C ++ program

Question

Code:

#include <iostream> #include <conio.h> using namespace std; int main () { cout << "Hello world!!!\n"; _getch(); return 0; }

Tell me, please, how to run the program in Microoft Visual Studio C ++ 2010, Express edition. OS Windows XP Professional 2008 Edition, Service Pack 3.

It gives the following error:

 ------ Построение начато: проект: 1, Конфигурация: Debug Win32 ------ 1.cpp c:\documents and settings\1\мои документы\visual studio 2010\projects\11\11\11.cpp(3): warning C4627: #include <iostream>: пропущен при поиске использования предкомпилированного заголовка Добавление директивы в "StdAfx.h" или перестройка предкомпилированного заголовка c:\documents and settings\1\мои документы\visual studio 2010\projects\11\11\11.cpp(4): warning C4627: #include <conio.h>: пропущен при поиске использования предкомпилированного заголовка Добавление директивы в "StdAfx.h" или перестройка предкомпилированного заголовка c:\documents and settings\1\мои документы\visual studio 2010\projects\11\11\11.cpp(14): fatal error C1010: непредвиденный конец файла во время поиска предкомпилированного заголовка. Возможно, вы забыли добавить директиву "#include "StdAfx.h"" в источник. ========== Построение: успешно: 0, с ошибками: 1, без изменений: 0, пропущено: 0 -=========

When creating a project, choose “create an empty project” and not with additional headers.
Or add #include "StdAfx.h" to the current file, if I'm not mistaken.

conio.h will not work in visual studio (at least in new versions).

conio.h is an outdated library, which is already in few places.

Use the system ("PAUSE") function to view the result.

 #include <iostream> using namespace std; int main () { cout << "Hello world!!!\n"; system("PAUSE"); return 0; }

With this problem should not arise.

In the studio there is Ctrl + F5, so that the window does not close.
I press Ctrl + F5, the message is displayed: "to continue, press any key ...".

I have not written in VS for a long time, but for the last time in VS 2005

Well, actually there he was sure to require a connection.

 #include "StdAfx.h"

Here, too, the compiler asks for the connection of this file.

At the beginning you need to add this line and all. otherwise, the program should work as planned.

When creating a project, you could tick the Empty Project. Then stdafx.h is not needed. - Janycz

Try this:

 #include "StdAfx.h" #include <Windows.h> //(для system("PAUSE");) #include <iostream> using namespace std; int main () { cout << "Hello world!!!\n"; while(1){ system("PAUSE"); } return 0; }

message: "to continue, press any key ...". after clicking the window closes. - siner
Well, yes, and you want it to not close at all? then add while (1) {} to system ("PAUSE"); and system ("PAUSE"); clean up. The program will loop and close only by pressing on the "X" - Alerr
the fact is that "hello world" is not displayed! immediately writes "to continue, press any key ..." - siner
uh, is not displayed? strange ... Try printf ("HW! \ n"); instead of cout << "Hello world !!! \ n"; - Alerr
well, the result is the same anyway ( - siner
