Hello world!

Hello, this my first post. I want to write a few strings about “Hello world” programs. Right now I’m passioned about R programming language. Code for Hello world program in R looks pretty trivial, for example: R cat('Hello, world!\n') 1 cat('Hello, world!\n') In Java language programs are a little more difficult, but still boring: Java public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, world!"); } } 12345 public class HelloWorld {    public static void main(String[] args) {        System.out.println("Hello, world!");    }} Let’s go to esoteric programming languages (esolang). An esolang is a programming language designed for fun or just to test the boundaries of computer programming languages. Classic esolang is Brainfuck, Hello World program looks pretty interesting: +++++ +++++ initialize counter (cell #0) to 10 [ use loop to set the next four cells to 70/100/30/10/40 > +++++ ++ add 7 to cell #1 > +++++ +++++ add 10 to cell #2 > +++ add 3 to cell #3 > + add 1 to cell #4 > ++++ add 4 to cell #5 <<<<< - decrement counter (cell #0) ] > ++ . print 'H' > + . print 'e' +++++ ++ . print 'l' . print 'l' +++ . print 'o' >>> ++++ . print ',' << ++ . print ' ' < +++++ +++ . print 'w' ----- --- . print 'o' +++ . print 'r' ----- - . print 'l' ----- --- . print 'd' > + . print '!' > . print '\n' 123456789101112131415161718192021222324 +++++ +++++ initialize counter (cell #0) to 10[ use loop to set the next four cells to 70/100/30/10/40> +++++ ++ add 7 to cell #1>...
