Language Translators And High Level Programming Languages

Language Translator:

Introduction:

Fig. Translator

Language translator is a program which is used to translate instructions that are written in the source code to object code i.e. from high-level language or assembly language into machine language.

There are 3 types of language translators. They are:

1. Assembler:
   

   Assembler is the language translator designed to translate assembly language program (source codes) into machine language program (object codes). The original assembly language program codes are called source codes and after translation, the final machine language program codes are called object codes.

2. Compiler:
   

   A compiler is a language translator that translates high-level languages program to machine language program. While translating, it checks the syntax (grammar of the source code) and translates it into object code at a single attempt. If any error is found, the compiler produces syntax errors and causes of the errors. The source code file must be syntax error-free for complete compilation process.

3. Interpreter:

   The interpreter is the language translator designed to translate high-level language program into machine language program, one instruction at a time. Unlike the compiler, it translates and executes one statement at a time before moving to another. If any error is encountered, the translation is halted and an error message is displayed.

List of High-level Programming Languages:

1. FORTRAN: FORTRAN stands for FORmula TRANslator. Developed by John Backus for IBM, in 1956, it is a very powerful language for scientific and engineering computations. FORTRAN IV, FORTRAN 77 (ANSI standard), FORTRAN 90, FORTRAN 95, etc. are some of its versions available.

2. BASIC: BASIC was developed in 1960 by John Kemeny and Thomas Kurtz, at Dartmouth College. Standing for Beginner’s All-Purpose Symbolic Instruction Code, it was the 1^st interpreted language and is a good language for beginners to learn initial programming skills.

3. COBOL: COBOL (Common Business Oriented Language) was developed specially for business data processing. Standardized by ANSI in 1968, it was developed for the US Department of defence by Grace Murray Hopper, in 1960.

4. C: C is a powerful, general-purpose high-level language which also has features of low-level programming. Earlier called as BPCL or simply B, it was developed by Dennis Ritchie, in 1970s at Bell Laboratory.

5. C++:Developed in the early 1980s by Bjarne Stroustrup, it is an updated version of C language. C++ is the super set of C language that supports object-oriented features and is extremely efficient.

6. PASCAL: PASCAL is a multipurpose programming language which is suitable for both scientific and business application. Developed in the early 1970s in Switzerland, by Niklaus Wirth at the Federal Institute of Technology, it was named after the 17th-century French Mathematician Blasé Pascal, on his honoring.

7. LISP: LISP which means LIST Processing is a suitable language for solving non-numeric data processing and is used in the field of the expert system, artificial intelligence and pattern recognition. It was developed by John McCarthy in the early 1960s, at IBM’s Laboratory.

9. NET: As an alternative for JAVA, NET is the Microsoft’s latest common platform which combines all powerful features of different languages into one environment, also called IDE (Integrated Development Environment). It is most commonly used for solving web based applications and distributed mobile applications. J#, C#, Visual Basic, Visual C++, etc. are some of its examples.

10. XML: XML (eXtensible Markup Language) is a web content development language which helps to manage sources’ documents in several different formats such as web page, PDF files, printable documents, etc. XML allows making their own tags to the users.

12. PHP: PHP stands for Hypertext Pre-processor. It is a very popular server site which scripts languages on UNIX / Linux system. It is also very popular for accessing databases like My SQL and Oracle which can be supported by Windows server too, by using 3^rd party software. It is an open source software.

15. Python: Python is a general purpose high-level programming language which supports multiple programming paradigms, including object-oriented features. It was developed in 1991 by Python Software Foundation and its main designer was Guido Van Rossum. It’s a free and open source software.
