The Imperative Paradigm . www.cs.scranton.edu/~mccloske/courses/cmps344/sebesta_chap1.html To improve your use of your existing programming language. Preliminaries. In PPL there is no type erasure at run-time. At present, thousand programming languages have been implemented. The Functional Paradigm. Be the first to rate this post. Programming languages allow the manipulation of data structures and the flow of execution of a program. The calculator supports programming in a new, Pascal -like programming language now named HP PPL (for Prime Programming Language, but originally also referred to as HP Basic) that also supports creating apps. PPL and Java code can be mixed and in-memory data can be exchanged between PPL and Java. Data types: Introduction, primitive, character, user-defined, array, associative, record, union, pointer and reference types, design and implementation uses related to these types. PPL is primarily an object-oriented language that supports typical OO-features such as multiple type inheritance, data encapsulation and polymorphism. This is easier to use, less error-prone and more flexible than method overloading. A programming language is an artificial language that can be used to control the behavior of computer. Progresses have been made to enrich languages and improve productivity. Click here to check all the JNTU Syllabus books, Follow us on Facebook and Support us with your Like. columns id, title, etc.). Perl is a programming language developed by Larry Wall, specially designed for text processing. 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. Variables. The compiler ensures that object references that could point to null at runtime are checked for null, before its features can be accessed (e.g. list) are shown in a table with one column per object attribute (e.g. Syntax and Semantics: general Problem of Describing Syntax and Semantics, formal methods of describing syntax – BNF, EBNF for common programming languages features, parse trees, ambiguous grammars, attribute grammars, denotational semantics and axiomatic semantics for common programming language features. Null-safety is natively built into the language. • Increased ability to express ideas. Generic types increase type safety and help to detect bugs at compile-time. Preliminary Concepts: Reasons for studying, concepts of programming languages, Programming domains, Language Evaluation Criteria, influences on Language design, Language categories, Programming Paradigms – Imperative, Object Oriented, functional Programming , Logic Programming. For example in PHP: It will display: 5 items. Complexity at the language level is kept at a minimum. Expressions And Statements. For example, if we test the type of an object, the compiler will ensure we didn't forget a sub-type. However, dynamic typing is supported through a built-in reflection mechanism. 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. C is a structured programming language developed in 1973 by computer programmer Dennis Ritchie at the Bell Laboratories. As per my knowledge programming languages are divided into 2; functional and object oriented. Upgrade to Prime and access all answers … principle of programming language unit 4 mcq. It is not the best option for writing low-level code applications, such as an OS kernel, a video game or fast number crunching programs. A programming language’s features include orthogonality or simplicity, available control structures, data types and data structures, syntax design, support for abstraction, expressiveness, type equivalence, and strong versus weak type checking, exception handling, and restricted aliasing. 79. Computer Technology (22618) Uploaded by. The Logic Paradigm . Expressions and Statements: Arithmetic relational and Boolean expressions, Short circuit evaluation mixed mode assignment, Assignment Statements, Control Structures – Statement Level, Compound Statements, Selection, Iteration, Unconditional Statements, guarded commands. The main reason behind the study of principle of programming language is to provide the good knowledge about the fundamentals to design, implementation, and application of the programming languages. Course Structure Unit 1 Introduction to Programming Languages Unit 2 Imperative and Procedural Programming Unit 3 Object Oriented Programming (Java) Unit 4 Advanced Java Unit 5 Case Studies of Programming Languages Because PPL is a JVM language the Java slogan 'write once, run anywhere' also holds for PPL. Programming Languages –Louden, Second Edition, Thomson. 20. This shields library components from some illegal (or unintended) usages and therefore helps to detect bugs early. Error-prone programming techniques are omitted in PPL as far as possible. A programming language is an artificial language used to create programs that express precise algorithms to make a computer perform computations.. Type Inference . The time needed to re-compile modified source code is kept to a minimum. Subprograms and Blocks: Fundamentals of sub-programs, Scope and lifetime of the variable, static and dynamic scope, Design issues of subprograms and operations, local referencing environments, parameter passing methods, overloaded subprograms, generic sub-programs, parameters that are sub-program names, design issues for functions user defined overloaded operators, coroutines. Download PPL Unit – 2 5 … Principles of Programming Languages Notes Pdf – PPL Notes Pdf book starts with the topics Subprograms and Blocks: Fundamentals of sub-programs, Scope and lifetime of the variable,general Problem of Describing Syntax and Semantics. Features of programming languages, and progresses. Scripting Language: Pragmatics, Key Concepts, Case Study: Python – values and types, variables, storage and control, Bindings and Scope, Procedural Abstraction, Data Abstraction, Separate Compilation, Module Library. At present, thousand programming languages have been implemented. Topic Description Download Link UNIT 1: Programming Language: Definition, History, Features. There are also special instructions and operators for writing null-safe code. Programming features: Stata's programming features allow you to add new commands to Stata. In this installment of Visual Studio 2015 Essentials, Walt Ritscher surveys the programming languages available, including C#, Visual Basic, C++, and F#, as well as some non-Microsoft languages that can be added to Visual Studio. These kind of checks are especially useful in big applications with lots of refactorings and many programmers working on the same codebase. Scripting Languages 19. Principles of Programming Language. Section 1.1: Why study programming languages? An Imperative -Based Object -Oriented Language: Java 18. Here is a simple example of a book object displayed by PPL's integrated Visual Object Explorer: You can set a breakpoint anywhere in the source code by simply inserting a debug instruction. Refinements in thinking about flow of control led to better language constructs for selection (i.e., if statements) and loops that force the programmer to be disciplined in the use of jumps/branching (by hiding them). It also supports some techniques typically (but not exclusively) found in functional programming languages such as first-class functions, lambdas/closures, sequential and parallel streams, immutability by default, and type inference. Uploaded 1 year ago . Contribute to nhthang99/cse-ppl development by creating an account on GitHub. The functional programming paradigms has its roots in mathematics and it is language independent. Therefore PPL applications run on any system that supports a Java Virtual Machine (JVM), such as MAC OS, Linux/Unix and Windows. Features and Characteristics of C Programming Language .

Many languages provide features that can be extremely useful when used properly but waste a large amount of time when used improperly. In the computer field, many languages need to be stated in an imperative form, while other programming languages utilize declarative form. Principles of Programming Language(PPL) Question Bank with solution UNIT I 1. Find out more. (ML 1973). Ans. Structuring The Data. Efficiency, Regularity. Here is the list of all the features that can be added to a language.
