Ada is a computer programming language. It was invented by Jean Ichbiah during the 1980s.^[1] It is very similar to the programming language Pascal. Ada offers various features to make a program 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.

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'.
