# Getting Started - Third Style¶

## Hello World¶

The next program prints the Hello World message on the screen (std-out).

load "stdlib.ring"

print("Hello World")


## Run the program¶

to run the program, save the code in a file, for example : hello.ring then from the command line or terminal, run it using Ring

ring hello.ring


## Create Executable File¶

Using Ring2EXE we can create executable file for our application

ring2exe hello.ring -static


The -static option will avoid the need to ring.dll|ring.so|ring.dylib

But since the stdlib.ring load libraries like (LibCurl, OpenSSL, MySQL, etc)

You will need these libraries!

To avoid the need to these libraries (If you don’t need stdlib classes)

Use stdlibcore.ring instead of stdlib.ring as in the next example

load "stdlibcore.ring"

print("Hello World")


Using stdlibcore.ring You can access the stdlib functions but not the stdlib classes.

if you want to use stdlib.ring and distribute your application

ring2exe hello.ring -dist -allruntime -noqt -noallegro


## Not Case-Sensitive¶

Since the Ring language is not case-sensitive, the same program can be written in different styles

Tip

It’s better to select one style and use it in all of the program source code

LOAD "stdlib.ring"
PRINT("Hello World")

Load "stdlib.ring"
Print("Hello World")


## Multi-Line literals¶

Using Ring we can write multi-line literal, see the next example

Load "stdlib.ring"
Print("
Hello
Welcome to the Ring programming language
How are you?

")


Also you can use the \n to insert new line and you can use #{variable_name} to insert variables values.

Load "stdlib.ring"
Print( "Hello\nWelcome to the Ring programming language\nHow are you?")


## Getting Input¶

You can get the input from the user using the getstring() function

Load "stdlib.ring"
cName = GetString()
Print("Hello #{cName}")


## No Explicit End For Statements¶

You don’t need to use ‘;’ or press ENTER to separate statements. The previous program can be written in one line.

Load "stdlib.ring"
Print("What is your name? ") cName=getstring() print("Hello #{cName}")


The comment starts with # or //

Multi-lines comments are written between /* and */
