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 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.
