9. CHAPTER
ELEVEN
GETTING STARTED - FIRST STYLE
11.1 Hello World
The next program prints the Hello World message on the screen (std-out).
see "Hello World"
11.2 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 the ring interpreter
ring hello.ring
11.3 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"
11.4 Multi-Line literals
Using Ring we can write multi-line literal, see the next example
See "
Hello
Welcome to the Ring programming language
How are you?
"
Also you can use the nl constant to insert new line and you can use the + operator to concatenate strings
123

10. Ring Documentation, Release 1.5.2
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?"
11.5 Getting Input
You can get the input from the user using the give command
See "What is your name? "
Give cName
See "Hello " + cName
11.6 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
11.7 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.
