There are several types and features of programming languages depending on their philosophy and objectives. 600.325/425 Declarative Methods - J. Eisner slide thanks to Tim Sheard, A User centered Approach to Language Design • Languages can be designed around several issues • To solve a computational problem • To make the implementers job easier • To make the programmer’s (user of the language) life easier • Which of these do you think is the most important? Examples include Pascal, Algol 68 and C. 1980s reducing complexity – object orientation, functional programming. ), e.g. java (object oriented) acl2 (propositional induction) algorithmic. Compiled languages are assembled into memory, with address locations and offsets precalculated, and then crafted into an “executable” program. Interpreted languages are evaluated one step at a time, with values and variables being determined dynamically at run time. We will also cover the Decision Tree, Naïve Bayes Classification and Support Vector Machine. movl #0x1,n compare: cmpl #oxa,n cgt end_of_loop acddl #0x1,n bra compare end_of_loop: HIGH LEVEL LANGUAGE • From the foregoing we can see that assembler language is not much of an improvement on machine code! Type-3 grammars must have a single non-terminal on the left-hand side and a right-hand side consisting of a single terminal or single terminal followed by a single non-terminal. • A program in this format is said to be in machine code. • 3.Poor quality software was produced. • In constrast, Imperative programs describe the details of HOW the results are to be obtained, in terms of the underlying machine model. Robotics Market- Overview. Explain the main differences between low-level and high-level languages. definition. Why use anything other than machine code? • In contrast, the programs in other languages make explicit HOW the “declarative knowledge” is used to solve the query. Assign-only-once variables. 1. (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 - - - - - - - - - - - - - - - - - - - - - - - - - - -. computers.

Eisner, Language Influences Programming Practice • Languages often strongly favor a particular style of programming • Object-oriented languages: a style making heavy use of objects • Functional languages: a style using many small side-effect-free functions • Logic languages: a style using searches in a logically-defined problem space 600.325/425 Declarative Methods - J. Eisner slide thanks to Adam Webber (modified), Fighting the Language • Languages favor a particular style, but do not force the programmer to follow it • It is always possible to write in a style not favored by the language • It is not usually a good idea… 600.325/425 Declarative Methods - J. Eisner slide thanks to Adam Webber (modified), Example: APL Factorial • An APL expression that computes X’s factorial • Expands X it into a vector of the integers 1..X, then multiplies them all together • (You would not really do it that way in APL, since there is a predefined factorial operator: !X) • Could be called functional, but has little in common with most functional languages    X 600.325/425 Declarative Methods - J. Eisner slide thanks to Adam Webber (modified), Programming Experience Influences Language Design • Corrections to design problems make future dialects, as already noted • Programming styles can emerge before there is a language that supports them • Programming with objects predates object-oriented languages • Automated theorem proving predates logic languages 600.325/425 Declarative Methods - J. Eisner slide thanks to Adam Webber (modified), Turing Equivalence • General-purpose languages have different strengths, but fundamentally they all have the same power • {problems solvable in Java}= {problems solvable in Fortran}= … • And all have the same power as various mathematical models of computation • = {problems solvable by Turing machine}= {problems solvable by lambda calculus}= … • Church-Turing thesis: this is what “computability” means 600.325/425 Declarative Methods - J. Eisner slide thanks to Adam Webber (modified), Declarative Programming • A logic program defines a set of relations.

The image which is given below describes the abstraction level of hardware. With this, many companies are showing interest and are investing on robots due to their benefits. • Even if the domain ultimately requires generating code for a specialized target environment, the embedded implementation can be used for modeling and simulation. • As a result: • 1.Schedule and cost estimates were often grossly inaccurate. “…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? john mitchell. Classification of Programming Languages 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… It is the most basic computer language necessary for any processor. • Many language features needed by a typical DSL • e.g. references:. Each programming language contains a unique set of keywords and syntax, which are used to create a set of instructions. Different languages have different purposes, so it makes sense to talk about different kinds, or types, of languages. Prasad (modified), Procedural vs Object-Oriented • New operations cause additive changesin procedural style, but require modifications to all existing “class modules” in object-oriented style. instructions use some english words (if, programming language paradigms correspond, CHRONOLOGICAL CLASSIFICATION OF PROGRAMMING LANGUAGES, 1980s reducing complexity – object orientation, functional.

A programming language defines a set of instructions that are compiled together to perform a specific task by the CPU (Central Processing Unit). Haskell or Lisp) is used. what is. ASSEMBLY LANGUAGE • Assembly language (or assembler code) was our first attempt at producing a mechanism for writing programs that was more palatable to ourselves. • A more problem-oriented (rather than machine-oriented) mechanism for creating computer programs would also be desirable. Prasad (modified), Imperative vs Non-Imperative • Functional/Logic programs specify WHAT is to be computed abstractly, leaving the details of data organization and instruction sequencing to the interpreter. Throughout this post, we will reveal a detailed classification of programming languages, with their features and differences that distinguish them from each other. Languages. Prasad (modified), Emphasis on procedural abstraction. Know that there are different levels of programming language: low-level language high-level language. Every programming language belongs to one of these category and sub-category. The user can also creates its own functions. Recursion. • The DSL can have its own optimizer that relies on domain-specific optimization rules so that performance bottlenecks can be addressed. • 2000s Genetic programming languages, DNA computing, bio-computing? procedural to object oriented.
