Ada Programming { UPPOG2 } torrents

Ada is a structured, statically typed, imperative, wide-spectrum, and object-oriented high-level computer programming language, extended from Pascal and other languages. It has built-in language support for explicit concurrency, offering tasks, synchronous message passing, protected objects, and non-determinism. Ada is an international standard; the current version (known as Ada 2012) is defined by ISO/IEC 8652:2012.

Ada was originally designed by a team led by Jean Ichbiah of CII Honeywell Bull under contract to the United States Department of Defense (DoD) from 1977 to 1983 to supersede the hundreds of programming languages then used by the DoD. Ada was named after Ada Lovelace (1815–1852), who is credited as being the first computer programmer.

Ada was originally targeted at embedded and real-time systems. The Ada 95 revision, designed by S. Tucker Taft of Intermetrics between 1992 and 1995, improved support for systems, numerical, financial, and object-oriented programming (OOP).

Notable features of Ada include: strong typing, modularity mechanisms (packages), run-time checking, parallel processing (tasks, synchronous Message passing, protected objects, and nondeterministic select statements), exception handling, and generics. Ada 95 added support for object-oriented programming, including dynamic dispatch.

The syntax of Ada minimizes choices of ways to perform basic operations, and prefers English keywords (such as "or else" and "and then") to symbols (such as "||" and "&&"). Ada uses the basic arithmetical operators "+", "-", "*", and "/", but avoids using other symbols. Code blocks are delimited by words such as "declare", "begin", and "end", whereas the "end" (in most cases) is followed by the identifier of the block it closes (e.g. if ... end if, loop ... end loop). In the case of conditional blocks this avoids a dangling else that could pair with the wrong nested if-expression in other languages like C or Java.
