Programming Language Programming Language "EASY" Rahul Kumar IIT Kanpur Outline • What is "EASY"? • Why use "EASY"? • Basic idea taken from NLP • Programming with NLP • How it works... • Example • Why can't computers be designed in "EASY" • Future Goals • References What is "EASY"? • A programming language • A programming language is a vocabulary and set of grammatical rules for instructing a computer or computing device to perform specific tasks. • The term programming language usually refers to high-level languages, such as BASIC, C, C++, COBOL, Java, FORTRAN, Ada, and Pascal. • Each language has a unique set of keywords (words that it understands) and a special syntax for organizing program instructions. Why use "EASY"? • Textbooks and scientific publications related to computer science and numerical computation can use English sentences in description of algorithms, so that all programmers can understand them. • A programmer who needs to implement a specific algorithm, especially an unfamiliar one, will often start with a pseudocode description, and then "translate" that description into the target programming language and modify it to interact correctly with the rest of the program. However, this won't be needed while using "EASY". • It can also be used in schools to teach programming to kids as they can use the words and syntax freely. Natural Language Programming • Natural language programming (NLP) is an ontology-assisted way of programming in terms of natural language sentences, e.g. English. A structured document with Content, sections and subsections for explanations of sentences forms a NLP document, which is actually a computer program. Programming with NLP • Do we really need computer languages to tell our computers what to do? Why can’t we just use natural human languages, like English, instead? • So the first question is: how might we represent these programs? • In principle we could use pretty much any programming language. But to make things practical, particularly at the beginning, we need a programming language with a couple of key characteristics. How it works... • The programming language is written in C. When it encounters a sentence, the keywords are recognized and then converted to a C program which is then executed. • This language will have lots of keywords. The keywords will be simple english words. Also it will contain various keywords with same meanings as there are synonyms in the english language. • For eg. If we have an array A and we give the command "sort in ascending order" or "arrange in ascending order", then both of them will perform the same task. Example • set the first number to 1 • set the second number to 2 • if the firstnumber is equal to the secondnumber • then set the sum to 5 • end if • Queue q • Enqueue x • Enqueue y • Add the top two elements of q Why can't Computers be designed in "EASY"? • At its most fundamental level, a computer provides a fixed set of instructions that it can execute. Each instruction has a number, which can be rendered in binary. The raw instructions themselves, if written down, are called machine language. • We invented a program called a compiler that takes a different language and turns it into machine language. • So while it's possible for a compiler to take ADD THE VALUES OF THE A AND B VARIABLES AND STORE THEM IN THE Z VARIABLE and convert this into machine language, it's really more efficient just to have a form of notation: Z := A+B Future Goals • The majority of activities performed by humans are done through language. • As technology is increasingly making the methods and platforms on which we communicate ever more accessible, there is an even greater need to understand the languages we use to communicate. • This language will take us a step closer towards a world where machines will understand human languages and respond.

    CCOOBBOOLL -- DDAATTAABBAASSEE IINNTTEERRFFAACCEE http://www.tutorialspoint.com/cobol/cobol_database_interface.htm Copyright © tutorialspoint.com As of now, we have learnt the use of files in COBOL. Now, we will discuss how a COBOL program interacts with DB2. It involves the following terms: Embedded SQL DB2 Application Programming Host Variables SQLCA SQL Queries Cursors Embedded SQL Embedded SQL statements are used in COBOL programs to perform standard SQL operations. Embedded SQL statements are preprocessed by SQL processor before the application program is compiled. COBOL is known as the Host Language. COBOL-DB2 applications are those applications that include both COBOL and DB2. Embedded SQL statements work like normal SQL statements with some minor changes. For example, that output of a query is directed to a predefined set of variables which are referred as Host Variables. An additional INTO clause is placed in the SELECT statement. DB2 Application Programming Following are rules to be followed while coding a COBOL-DB2 program: All the SQL statements must be delimited between EXEC SQL and END-EXEC. SQL statements must be coded in Area B. All the tables that are used in a program must be declared in the Working-Storage Section. This is done by using the INCLUDE statement. All SQL statements other than INCLUDE and DECLARE TABLE must appear in the Procedure Division. Host Variables Host variables are used for receiving data from a table or inserting data in a table. Host variables must be declared for all values that are to be passed between the program and the DB2. They are declared in the Working-Storage Section.

  • Object-Oriented Programming Basics with Java
    Object-Oriented Programming Object-Oriented Programming Basics With Java In his keynote address to the 11th World Computer Congress in 1989, renowned computer scientist Donald Knuth said that one of the most important lessons he had learned from his years of experience is that software is hard to write! Computer scientists have struggled for decades to design new languages and techniques for writing software. Unfortunately, experience has shown that writing large systems is virtually impossible. Small programs seem to be no problem, but scaling to large systems with large programming teams can result in $100M projects that never work and are thrown out. The only solution seems to lie in writing small software units that communicate via well-defined interfaces and protocols like computer chips. The units must be small enough that one developer can understand them entirely and, perhaps most importantly, the units must be protected from interference by other units so that programmers can code the units in isolation. The object-oriented paradigm fits these guidelines as designers represent complete concepts or real world entities as objects with approved interfaces for use by other objects. Like the outer membrane of a biological cell, the interface hides the internal implementation of the object, thus, isolating the code from interference by other objects. For many tasks, object-oriented programming has proven to be a very successful paradigm. Interestingly, the first object-oriented language (called Simula, which had even more features than C++) was designed in the 1960's, but object-oriented programming has only come into fashion in the 1990's.

  • The Machine That Builds Itself: How the Strengths of Lisp Family
    Khomtchouk et al. OPINION NOTE The Machine that Builds Itself: How the Strengths of Lisp Family Languages Facilitate Building Complex and Flexible Bioinformatic Models Bohdan B. Khomtchouk1*, Edmund Weitz2 and Claes Wahlestedt1 *Correspondence: [email protected] Abstract 1Center for Therapeutic Innovation and Department of We address the need for expanding the presence of the Lisp family of Psychiatry and Behavioral programming languages in bioinformatics and computational biology research. Sciences, University of Miami Languages of this family, like Common Lisp, Scheme, or Clojure, facilitate the Miller School of Medicine, 1120 NW 14th ST, Miami, FL, USA creation of powerful and flexible software models that are required for complex 33136 and rapidly evolving domains like biology. We will point out several important key Full list of author information is features that distinguish languages of the Lisp family from other programming available at the end of the article languages and we will explain how these features can aid researchers in becoming more productive and creating better code. We will also show how these features make these languages ideal tools for artificial intelligence and machine learning applications. We will specifically stress the advantages of domain-specific languages (DSL): languages which are specialized to a particular area and thus not only facilitate easier research problem formulation, but also aid in the establishment of standards and best programming practices as applied to the specific research field at hand. DSLs are particularly easy to build in Common Lisp, the most comprehensive Lisp dialect, which is commonly referred to as the “programmable programming language.” We are convinced that Lisp grants programmers unprecedented power to build increasingly sophisticated artificial intelligence systems that may ultimately transform machine learning and AI research in bioinformatics and computational biology.

  • 10 Programming Languages You Should Learn Right Now by Deborah Rothberg September 15, 2006 8 Comments Posted Add Your Opinion
    10 Programming Languages You Should Learn Right Now By Deborah Rothberg September 15, 2006 8 comments posted Add your opinion Knowing a handful of programming languages is seen by many as a harbor in a job market storm, solid skills that will be marketable as long as the languages are. Yet, there is beauty in numbers. While there may be developers who have had riches heaped on them by knowing the right programming language at the right time in the right place, most longtime coders will tell you that periodically learning a new language is an essential part of being a good and successful Web developer. "One of my mentors once told me that a programming language is just a programming language. It doesn't matter if you're a good programmer, it's the syntax that matters," Tim Huckaby, CEO of San Diego-based software engineering company CEO Interknowlogy.com, told eWEEK. However, Huckaby said that while his company is "swimmi ng" in work, he's having a nearly impossible time finding recruits, even on the entry level, that know specific programming languages. "We're hiring like crazy, but we're not having an easy time. We're just looking for attitude and aptitude, kids right out of school that know .Net, or even Java, because with that we can train them on .Net," said Huckaby. "Don't get fixated on one or two languages. When I started in 1969, FORTRAN, COBOL and S/360 Assembler were the big tickets. Today, Java, C and Visual Basic are. In 10 years time, some new set of languages will be the 'in thing.' …At last count, I knew/have learned over 24 different languages in over 30 years," Wayne Duqaine, director of Software Development at Grandview Systems, of Sebastopol, Calif., told eWEEK.
