We all know that when people learn a new programming language, one of their first tasks is to learn how to code, “Hello World!” Being a very simple program to be understood easily in most computer languages, it is often used to illustrate the basic syntax of a programming language for a working program. In addition, “Hello world” program is also used to make sure that a language’s compiler, development environment, and run-time environment are correctly installed.
Today, we thought that we should share the ‘hello world’ program in 26 different programming languages. Let’s take a look at these programs.
1. C
#include
int main(void)
{
puts(“Hello, world!”);
}
2. C++
#include
int main()
{
std::cout << “Hello, world!”;
return 0;
}
3. C#
using System;
class Program
{
public static void Main(string[] args)
{
Console.WriteLine(“Hello, world!”);
}
}
4. Java
import javax.swing.JFrame; //Importing class JFrame
import javax.swing.JLabel; //Importing class JLabel
public class HelloWorld {
public static void main(String[] args) {
JFrame frame = new JFrame(); //Creating frame
frame.setTitle(“Hi!”); //Setting title frame
frame.add(new JLabel(“Hello, world!”));//Adding text to frame
frame.pack(); //Setting size to smallest
frame.setLocationRelativeTo(null); //Centering frame
frame.setVisible(true); //Showing frame
}
}
5. JavaScript
document.write(‘Hello, world!’);
6. HTML
Hello World!
7. Python
print “Hello, world!”
8. Pascal
program HelloWorld;
begin
WriteLn(‘Hello, world!’);
end.
9. Ruby
puts “Hello, world!”
10. Visual Basic .NET
Module Module1
Sub Main()
Console.WriteLine(“Hello, world!”)
End Sub
End Module
11. MatLab
disp (‘Hello, world!’)
12. jQuery
$(“body”).append(“Hello world!”);
13. Bash
echo “Hello World”
14. Perl 5
print “Hello, world!”;
15. Basic
PRINT “Hello, world!”
16. Objective-C
#import
#import
int main(void)
{
NSLog(@”Hello, world!”);
return 0;
}
17. XSLT
Hello World
18. CoffeeScript
console.log ‘Hello, world!’
19. Logo
print [Hello, world!]
20. VBScript
MsgBox “Hello, World!”
21. Clipper
? “Hello World”
22. Delphi
program HelloWorld;
begin
Writeln(‘Hello, world!’);
end.
23. Julia
println(“Hello world!”)
24. Processing
void setup()
{
println(“Hello, world!”);
}
25. R
cat(‘Hello, world!’)
26. Swift
println(“Hello, world!”)
While small test programs existed since the development of programmable computers, the tradition of using the phrase “Hello world!” as a test message was influenced by an example program in the seminal book, The C Programming Language, by Kernighan and Ritchie.
