First introduced in the BCPL programming
language "Hello World!" is a
software
program
or script
used to help introduce someone to a
programming
language,
to test a programming language, and/or to test a
compiler
of a programming language. The few lines of code print the message:
"Hello World!" to the
computer
screen
and give the user a basic understanding of how to print something to
the screen, compile, and run the program or script.
Below is an example of how to print "Hello World!" in
Perl.
|
#!/usr/bin/perl
print "Hello
World!\n";
|
- A great collection of printing "Hello World!" to the screen in
over 290 different programming languages can be
found here.
