This means that when you create a variable you reserve some space in memory. Features of first generation computers: Technology used: vacuum tube; Machines languages were used to instruct the computer. marjan sirjani course web site: http://ut.ac.ir/classpages/programminglanguages/. power and data cables. Computer Science Examples include Pascal, Algol 68 and C. 1980s reducing complexity – object orientation, functional programming. 600.325/425 Declarative Methods - J. Eisner slide thanks to Jim Greenlee (modified), What is a programming language? To facilitate discussion on any subject it is convenient to group together similar facets of the subject according to some grouping notion. CHRONOLOGICAL CLASSIFICATION OF PROGRAMMING LANGUAGES 1940s Prelingual phase: Machine code 1950s Exploiting machine power: Assembler code, Autocodes, first version of Fortran 1960s Increasing expressive power: Cobol, Lisp, Algol 60, Basic, PL/1 --- but most “proper” programming still done in assembly language. LANGUAGE LEVELS OF ABSTRACTION . Programming Languages - . Programming Languages - . Emphasis on data abstraction. Bottom-up design; Reusable libraries. 600.325/425 Declarative Methods - J. Eisner slide thanks to Tim Sheard, Embedded Languages • In embedded approach, each domain concept is realized directly as a host-language construct: • domain operators are host-language procedures, • domain types are host-language user-defined data types, etc. john mitchell. High-level languages, that are anything machine-independent 4. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Program: a sequence of instructions for a von Neumann m/c. Haskell or Lisp) is used. good question from a student: what does the following mean? While doing programming in any programming language, you need to use various variables to store various information. Procedural vs Object-Oriented 600.325/425 Declarative Methods - J. Eisner slide thanks to T.K. • “high-level languages are less efficient” • Unacceptable start-up costs. introduction to linguistics 2. defining language. However, there also exists another category known as Middle level language. programmable, general-purpose, Programming Languages - . Non Procedural Languages. power supply. programming languages. • 3.Poor quality software was produced. In these languages, programs are written by means of the memory and registers available on the computer. 2] High Level Language. programming languages are classified into various, Typological Classification of Languages - . Compiled languages are assembled into memory, with address locations and offsets precalculated, and then crafted into an “executable” program. most marked. Machine languages, that are interpreted directly in hardware 2. Looks like you’ve clipped this slide to already. Know that there are different levels of programming language: low-level language high-level language. (Bells Labs) • string processing • powerful pattern matching PL/I 1963-1964, IBM • general purpose programming • powerful pattern matching • planned successor to FORTRAN, Algol 60, COBOL • user-defined exceptions • multi-tasking Simula67 1967, Dahl & Nygaard • simulation • class concept for data abstraction • persistent objects • inheritance of properties, © 2020 SlideServe | Powered By DigitalOfficePro, - - - - - - - - - - - - - - - - - - - - - - - - - - - E N D - - - - - - - - - - - - - - - - - - - - - - - - - - -. This “knowledge” can be used in various ways by the interpreter to solve different queries. Computer programming language can be classified into two major categories: •Low Level •High Level Low Level Languages The languages which use only primitive operations of the computer are known as low language.
