Hello world
Hello World
Hi all,
This is my new tech blog which i am starting from now on. I am yet another computer science from NIT, Trichy. Think the above statement implies many things like
I am jobless 
I dont/neednot/never attend classes regularly
I have never gained anything from what the college teaches me
Think that’s enough about me . Being a compsci student , i would like to start with an simple “Hello World” in comp sci style .
So here i go, Hello World in Hello World in few languages. I have used most of the languages, but few i just copy pasted the code after googling for them
* ADA
with Text_To; use Text_To
procedure hello is
begin
put(“Hello World”);
end hello
* BASIC
10 REM Hello, World in BASIC
20 print “Hello, World!”
