FOURTEEN
GETTING STARTED - FIRST STYLE
14.1 Hello World
The next program prints the Hello World message on the screen (std-out).
see "Hello World"
14.2 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
14.3 Create Executable File
Using Ring2EXE we can create executable file for our application
ring2exe hello.ring -static
14.4 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
SEE "Hello World"
See "Hello World"
14.5 Multi-Line literals
Using Ring we can write multi-line literal, see the next example
167

8. Ring Documentation, Release 1.8
See "
Hello
Welcome to the Ring programming language
How are you?
"
Also you can use the nl variable to insert new line and you can use the + operator to concatenate strings
As we have NL for new lines, we have Tab and CR (Carriage return) too!
Note: nl value means a new line and the actual codes that represent a newline is different between operating systems
See "Hello" + nl + "Welcome to the Ring programming language" +
nl + "How are you?"
14.6 Getting Input
You can get the input from the user using the give command
See "What is your name? "
Give cName
See "Hello " + cName
14.7 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.
See "What is your name? " give cName see "Hello " + cName
14.8 Using ? to print expression then new line
It’s common to print new line after printing an expression, We can use the ? operator to do that!
Example:
? "Hello, World!"
for x = 1 to 10
? x
next
Output:
Hello, World!

14.9 Writing Comments
We can write one line comments and multi-line comments
The comment starts with # or //
Multi-lines comments are written between /* and */
/*
Program Name : My first program using Ring
Date : 2016.09.09
Author : Mahmoud Fayed
*/
See "What is your name? " # print message on screen
give cName # get input from the user
see "Hello " + cName # say hello!
// See "Bye!"
Note: Using // to comment a lines of code is just a code style.

GETTING STARTED - SECOND STYLE
15.1 Hello World
The next program prints the Hello World message on the screen (std-out).
put "Hello World"
15.2 Run the program
