An Introductory Guide to the Ada Programming Language

DESCRIPTION

Discover the Ada programming language, a highly structured and robust language developed for systems requiring reliability and efficiency. Tracing its history from Ada Lovelace to modern implementations like Ada 2012, this guide highlights its key features such as strong typing, modularity, concurrency, and exception handling. Learn about historical figures, significant milestones, and practical examples of Ada code. Explore how Ada compares to other languages, including C++, and understand its applications in industries like aerospace and defense.

  2. What is ADA？ 啊哒！！

  3. contents History Language Features Others

  4. History Jean David Ichbiah  (25 March 1940 – 26 January 2007) United States Department of Defense Ada Lovelace (10 December 1815 – 27 November 1852)

  5. History --Ada 83 --Ada 95 --Ada 2005（Ada 95 Amendment 1） and Rationale --Ada 2012 and Rationale

  6. Language Features Strong typing Modularity mechanisms Run-time checking Parallel processing Exception handling Generics Object-oriented programming

  7. Language Features Hello World withAda.Text_IO:useAda.Text_IO; procedureHellois begin Put_Line("Hello, world!"); end Hello;

  8. Language Features Data type type Day_type is range 1 .. 31; type Month_type is range 1 .. 12; type Year_type is range 1800 .. 2100; type Hours ismod 24; type Weekday is (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday); type Date is record Day : Day_type; Month : Month_type; Year : Year_type; end record;

  9. Language Features Packages, procedures and functions -- example.ads packageExampleis typeNumberis range1.. 11; procedurePrint_and_Increment (j:inoutNumber); end Example;

  10. -- example.adb withAda.Text_IO; packagebody Example is i : Number := Number'First; procedurePrint_and_Increment (j: in out Number) is function Next (k: in Number) return Number is begin return k + 1; end Next; begin Ada.Text_IO.Put_Line ( "The total is: " & Number'Image(j) ); j := Next (j); endPrint_and_Increment; begin whilei < Number’Lastloop Print_and_Increment(i) endloop; end Example;

  11. Language Features Concurrency procedureTrafficis … task body Airplane is begin … end; begin for I in Airplane_ID’Range loop New_Airplane := new Airplane(I) delay 4.0 end loop end Tafiic;
