Ada (programming language)

Ada is a computer programming language. It was invented by Jean Ichbiah during the 1980s. It is very similar to the programming language Pascal. Ada offers various features to make a programme as safe as possible. That is why it is often used in systems, where an error can be very dangerous. Ada is an international standard.
"Hello world" in Ada.
Example of a Hello world program in Ada:
with Ada.Text_IO;
procedure Hello is
begin
 -- output of Text "Hello, world!".
 Ada.Text_IO.Put_Line("Hello, world!");
end Hello;
ADA is a reference to the mathematician Ada Lovelace, well known for her work with Charles Babbage on the first computer, The Analytical Engine, and her short book 'Flyology'.
