In addition, you will discover which is the best language for web programming. LANGUAGE LEVELS OF ABSTRACTION . marjan sirjani course web site: http://ut.ac.ir/classpages/programminglanguages/. The programming of first generation computers was done in machine languages (0s and 1s). • To address these problems the discipline of software engineering came into being. Haskell or Lisp) is used. • The DSL can be ``restricted" to enforce constraints on what can be expressed. But in addition, we should add: Helps bridge gap between developer and user 600.325/425 Declarative Methods - J. Eisner slide partly thanks to Tim Sheard, Potential Disadvantages of DSL’s • Performance may be poor. some key concepts. With this, many companies are showing interest and are investing on robots due to their benefits. Computer Science - Classification of Programming Languages Programming Languages are broken down into High level and Low level languages. Assign-only-once variables. Program: a collection of function definitions (m/c independent). Introduction:. In these languages, programs are written by means of the memory and registers available on the computer. what is a computer? • Hence the advent of high(er) level languages commencing with the introduction of “Autocodes”, and going on to Algol, Fortran, Pascal, Basic, Ada, C, etc. support for procedural abstraction; modules; etc will already exist in the host language; • It is straightforward to integrate code from multiple DSLs if they share the same host implementation. LOW level language 2. programming language classification according to dr. deryck brown, Programming Languages - . Each programming language contains a unique set of keywords and syntax, which are used to create a set of instructions. Computer programming languages are no exception. Classification of programming language based on level and generation of PL. The user can also creates its own functions. Classification in R Programming: The all in one tutorial to master the concept! Languages. • 2000s Genetic programming languages, DNA computing, bio-computing? • A more problem-oriented (rather than machine-oriented) mechanism for creating computer programs would also be desirable. Programming Languages - . computers. Prasad (modified), Program: a sequence of instructions for a von Neumann m/c. Throughout this post, we will reveal a detailed classification of programming languages, with their features and differences that distinguish them from each other. PLC Programming Language Classification Chart. Suited for programming in the large. Features of first generation computers: Technology used: vacuum tube; Machines languages were used to instruct the computer. Compiled languages are assembled into memory, with address locations and offsets precalculated, and then crafted into an “executable” program. Every programming language belongs to one of these category and sub-category. Since the starting of programming language, it is classified into three categories. All the computer programming languages are broadly classified into the following; Machine level Language; … ?- sum(1,2). 10. high level languages. Prasad (modified), Emphasis on procedural abstraction. Now customize the name of a clipboard to store your clips. • new language(s) for every domain • Language creep/bloat. languages are described by their types rather than by their, The Classification of Languages - . Machine, Assembler and High Level Languages … System languages, that are designed for writing low-level tasks, like memory and process management 5. (Bal and Grune 94) Level Instructions Memory handling Low level languages Simple machine-like instructions Direct memory access and allocation High level languages Expressions and explicit flow of control Memory access and allocation through operators Very high level languages Fully abstract machine Fully hidden memory access and automatic allocation, Programming language paradigms correspond to natural language Imperative: commands “copy the value of X into Y” Functional: noun phrases “the sum of X and Y” Logic: subject/predicate sentences (declarations) “X is greater than Y”, Computational Paradigms Imperative: manipulate an abstract machine • variables naming memory locations • arithmetic and logic operators • reference, evaluate, assignment operators Fits von Neumann architecture closely Key operation: assignment and control-flow, Computational Paradigms Functional: express problem solution as operations on data • no named memory locations • no assignment operators (no side-effects) • value binding through parameter passing Key operation: function application, Computational Paradigms Object-oriented: organise program as collection of interacting entities with notion of identity • data and operations encapsulated • emphasis on data abstraction Key operation: message passing, Computational Paradigms Logic: formally specify problem solution • program states what properties a solution must have • program does not state how to calculate solution • underlying solution engine Key operation: unification, SUM = 0 DO 11 K = 1, N SUM = SUM + 2 * K 11 CONTINUE sum = 0; for (k=1; k<=N; k++) sum += 2*k; sum := 0; for j :=1 to N do sum := sum + 2*k; Imperative Languages Problem: sum twice the numbers from 1 to N FORTRAN C Algol, class myset : public Set { public: myset() {} int sum() { int s = 0; SetEnumeration e = new SetEnumeration(this); while (e.hasMoreElements()) s += ((Integer) e.nextElement()).intValue(); return s; } } Object-oriented Languages Problem: sum twice the numbers from 1 to N C++, fun sum(n) = if n = 0 then 0 else 2 * n + sum (n - 1); sum(4) evaluates to 20 Functional Languages Problem: sum twice the numbers from 1 to N ML (define (sum n) (if (= n 0) 0 (+ (* 2 n) (sum (- n 1))) ) ) (sum 4) evaluates to 20 Scheme, sum(0,0). Interpreted languages are evaluated one step at a time, with values and variables being determined dynamically at run time. Classification of Programming Languages 1. types of languages. • more features added incrementally • Language design/implementation is hard!! S = 420 Logic Languages Problem: sum twice the numbers from 1 to N Prolog, Advantages of the DSL Approach • Programs in the target domain are: • more concise • quicker to write • easier to maintain • easier to reason about • written by non-programmers Contribute to higher programmer productivity Dominant cost in large SW systems Formal verification, program transformation, compiler optimization These are the same arguments in favor of any high-level language! While doing programming in any programming language, you need to use various variables to store various information. What is a Programming Language Why do we need a programming language Why are there so many programming languages Generations of programming languages. Students should understand that most computer programs are written in high-level languages and be able to explain why this is the case. Looks like you’ve clipped this slide to already. • Embedding may be thought of as rapid prototyping. PROGRAMMING LANGUAGES - The world of software development. • In contrast, the programs in other languages make explicit HOW the “declarative knowledge” is used to solve the query. • 3.Poor quality software was produced. programming languages are classified, Programming Languages - . • 2-5 years typical for new language 600.325/425 Declarative Methods - J. Eisner slide thanks to Tim Sheard, Scripting Languages vs. DSL’s • Scripting languages are DSL’s. • As a result: • 1.Schedule and cost estimates were often grossly inaccurate. • Automated construction tools for interpreters and compilers can make building a stand-alone system cheaper; while many such tools exist, some important ones are still missing. motivation why study programming languages?

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. http://dgitacademy.com | There are lots of different computer programming languages, like Python, C, Java, and Go. Non procedural programming languages are also known as fourth generation languages. Sometime it’s also known as level and/or generation of programming language. Emphasis on data abstraction. Computation by term rewriting. Special Programming Languages. good question from a student: what does the following mean? Programming Languages - Cs 242. programming languages. “…a set of conventions for communicating an algorithm.” - Horowitz Purposes • specifying algorithms and data • communicating to other people • establishing correctness this and following slides thanks to James Montgomery, Why use anything other than machine code? dialect and language defining, Programming Languages - . We will also cover the Decision Tree, Naïve Bayes Classification and Support Vector Machine. CLASSIFICATION OF PROGRAMMING LANGUAGES. programming languages. The image which is given below describes the abstraction level of hardware. Classification of programming languages: • Machine, Assembler and High Level Languages • Chronological order of development • Generations • Levels of abstraction (from machine level) • Declarative v Non-declarative • Paradigms. THE SOFTWARE CRISIS • The phrase software crisis alludes to a set of problems encountered in the development of computer software during the 1960s when attempting to build larger and larger software systems using existing development techniques.

Prasad (modified), Further Perspective In addition to labels of functional, procedural, and OO languages, we might also categorize languages based on whether they are interpreted or compiled(or even a hybrid). It is the most basic computer language necessary for any processor. See our User Agreement and Privacy Policy. • design time, implementation, documentation • Tower of Babel. introduction. Computer Science (A Level) Classification of Programming Languages 2. Classification of Programming languages are languages When it comes to mechanics of the task, learning to speak and use a programming language is in many ways like learning to speak a human language In both kind of languages you have to learn new vocabulary, syntax and semantics (new words, sentence structure and meaning) And both kind of language require considerable practice to make perfect. Lect 1. introduction to programming languages, Appraisal (Self Assessment, Peer Assessment, 360 Degree Feedback), High Level Languages (Imperative, Object Orientated, Declarative). PROGRAMMING LANGUAGES) Hybrid Implementation Process Unit-1(PRINCIPLES OF 1-30 PROGRAMMING LANGUAGES) Just-in-Time Implementation Systems Initially translate programs to an intermediate language Then compile the intermediate language of the subprograms into machine code when they are called A programming language defines a set of instructions that are compiled together to perform a specific task by the CPU (Central Processing Unit). sum(N,S) :- NN is N - 1, sum(NN, SS), S is N*2 + SS.
