History Of Pascal Language

PASCAL language first developed in the early 70's by NICLAUS Wirth at the Technical University, Zurich - Switzerland. In the end, in 1971, one of the developers ALGOL has successfully developed a new programming language called PASCAL, which adopted the name of French scientists in the 17th century Blaise Pascal. PASCAL is a programming language that is structured, high level programming language, as well as easy for the programmer to specify the desired data type.

In the early 1980s, PASCAL programming language has become standard in many universities. There are two events that cause PASCAL become very popular at the time of PASCAL as the language used to create applications / software for the purpose of the exam in some schools, as well as the release of Turbo Pascal compiler by Borland International for a computer company IBM. Until now, Turbo Pascal 7.0 has reached release there's even a run on the Windows platform (Turbo Pascal for Windows). There is also a variant of the Turbo Pascal which is more open source of Free Pascal. 

The advantages of the Pascal programming language are:

• Standard data types, standard data types that are already available in most programming languages. Pascal has a standard data types: Boolean, integer, real, char, string,
• User defined Data Types, programmers can create other data types derived from standard data types.
• Strongly-typed, the programmer must specify the data type of a variable, and variables can not be used to store data types other than the specified format.
• Structured, has a syntax that allows the writing of programs broken down into smaller functions (procedures and functions) that can be used repeatedly.
• Simple and expressive, has a simple structure and very close to human language (English) so it is easy to learn and understand.

PASCAL language is also the language used as the standard programming language for the national team's Olympic Computer Indonesia (TOKI). In addition, PASCAL language is still used in the IOI (International Olympiad in Informatics). However, at this time. PASCAL has started being abandoned. Most programmers today prefer C / C + + and Java because of better support for object-oriented programming.


Pascal Compiler:

Some compilers including Turbo Pascal Pascal 7.0, Turbo Pascal For Windows (TPW), and Free Pascal (FPC). Use Free Pascal if you want the compiler pascal Click here to pdfsecara free version. You can download it directly on freepascal.org to get it. Moreover, if initially FPC runs on 16-bit only, now in addition to the 32-bit, FPC has also been able to run on 64-bit platforms.
