Hello Word in C Language

I use Visual Studio 2005 (including C ++, which is actually vc8.0). If vc is used, it should be similar. Next I will explain how to compile and run Hello World in my environment!
1. Open vc from the Start Menu or in a shortcut. Choose file> new> project (or file> new> project ).
2. In the displayed dialog box, select visual c ++ on the left, win32 on the right, win32 console application (or win32 console Program), and name (or name) on the bottom) enter Helloworld (or your favorite name, which is the project name) and click OK (or OK ).
3. Click next or set the application settings program. Select console application console program for the application type program. Select the Empty project (Empty project or Empty project forgot Chinese) in the additional options of additional options, and click finish.
4. Open solution explorer to browse (the Chinese name is missing) (if not, you can call it out from view> solution explorer), right-click the source file, select add to add a new item.
5. Select code on the left and C ++ file on the right. Enter the name HelloWorld or your favorite name in the name column, and click add.
6. Copy the code to HelloWorld. cpp
# Include <stdio. h>
# Include <stdlib. h>
Int main (void)
{
Printf ("Hello World! \ N ");
System ("pause ");
Return 0;
}
Copy to HelloWorld. cpp.
7. Select build> build solution (create> build solution) on the menu, or press F7. Run debug-> start debuging (debug-> start debugging) or press F5. Or press f5. However, it is generally followed by f7.
In this way, you can compile and run the program Helloworld. The main problem is to create a new project first.

The younger brother just learned C # and asked how to write the simplest hello word C # program in VS2008, create a project, and select the program type

Console Application

1. Beginners

Public class HelloWorld
{
Public static void Main ()
{
System. Console. WriteLine ("hello world ");
}
}

2. Improved HELLO WORLD

Using System;
Public class HelloWorld
{
Public static void Main ()
{
Console. WriteLine ("hello world ");
}
}

3. command line format

Using System;
Public class HelloWorld
{
Public static void Main (string [] args)
{
Console. WriteLine (args [0]);
}
}

4. Constructor

Using System;
Public class HelloWorld
{
Public HelloWorld ()
{
Console. WriteLine ("hello world ");
}

Public static void Main ()
{
HelloWorld hw = new HelloWorld ();
}
}

5. Object-oriented

Using System;
Public class HelloWorld
{
Public void helloWorld ()
{
Console. WriteLine ("hello world ");
}

Public static void Main ()
{
HelloWorld hw = new HelloWorld ();
Hw. HelloWorld ();
}
}

6. From other classes

Using System;
Public class HelloWorld
{
Public static void Main ()
{
HelloWorldHelperClass hwh = new HelloWorldHelperClass ();
Hwh. writeHelloWorld ();
}
}

Public class HelloWorldHelperClass
{
Public void writeHelloWorld ()
{
Console. WriteLine ("Hello World ");
}
}

7. Inheritance

Abstract class HelloWorldBase
{
Public abstract void writeHelloWorld ();
}

Class HelloWorld: HelloWorldBase
{
Public override void writeHelloWorld ()
{
Console. WriteLine ("Hello World ");
