The first generation programming language is also called low-level programming language because they were used to program the computer system at a very low level of abstraction. Advantages of first generation language 1. A type system is a syntactic method for enforcing levels of abstraction in programs. The book concentrates on the use of type systems in programming languages, at the expense of some topics (such After providing some background on the λ-calculus and basic A comprehensive introduction to type systems and programming languages. Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. PROG0101 Fundamentals of Programming 5 programming languages: C Programming Java Programming Python Programming A major part of the tutorial has been explained by taking C as programming language and then we have shown how similar concepts work in Java and Python. A type system is a syntactic method for automatically checking the absence of certain erroneous behaviors by classifying program phrases according to the kinds of values they compute. The study of type systems for programming languages has emerged over the past decade as one of the most active areas of computer science research, with impor-tant applications in software engineering, programming language design, high-performance compiler implementation, and security of … Ada was one of the first widely-used languages to have a language construct representing an abstraction (a package), an abstract data type (a private type), multi-threading (tasks), generic templates, exception handling, strongly-typed separate compilation, subprogram inlining, etc. There is an unfortunate tendency in Computer Science to re-invent language features without carefully studying previous work. Different languages have different purposes, so it makes sense to talk about different kinds, or types, of languages. The first half (through to Chapter 15) is relevant to this course, and some of the later material relevant to the Part II Types course. Recent work on dependent types in programming languages can be roughly divided into two streams: •designing languages with full dependent types (a.k.a. • A vocabulary and set of grammatical rules (syntax) for instructing a computer to perform specific tasks. System languages, that are designed for writing low-level tasks, like memory and process management 5. ÿÕýú݈½8I&óaò†–g èÐBQڈ[j,D’¿¸ÆäÆÙ¾Ž(t %ùí•\q‡Û`i8Û×u’íµÓe='Âp)Zªœ4ä¯ýî8Š¢t¢~¨¿ÏÌ\–H/š­é=ÃÚ ëë¬gáEز~. <> {vèÀV­F80«k¼†I¸‚þö:ª›žÎ ºîÙ»,Žä\a.KnÄodÂB#;6Z)‰~ýó¬4‡Ó«š½-‘‰­á {ù¼’ gîšÄpº&Yš¤…ðÅU¿m[õÇ Q$êÓ4†Ç•*Ö *|Q9Æ~@T$vnñA ¶ª˜”^Ä¢}¿÷fº¸¼ì¦ƒéôÕ\ð#Ž4h¥µF"íÁ“†Äjدâèólãaó»Fk‡Úž­/âècÁ( ðÝ ý Every year there are a number of programming languages are implemented, but few languages are becoming very popular which may used by a professional programmer in their career. At the end of the chapter, you should have learned: what programming paradigms are; an overview of different programming languages and the background knowledge of these There are two types of programming languages, which can be categorized into the following ways: 1.Low level language: Machine language (1GL), Assembly language (2GL) 2. “doing it the hard way”) — e.g., Cayenne •controlling dependent types to ensure tractable typechecking (and good interaction with nontermination, effects, etc.) High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. The machine language also referred to as the native language of the computer system is the first generation programming language. Consequently, the notation develops into a programming language with many of the bad features of old, long-since rejected programming languages. Types and Programming Languages is designed for an advanced undergraduate or graduate course and assumes some familiarity with functional programming. endstream Command-line interface (CLI) languages are also called batch languages or job control languages. •Type checking •Easier to debug •You may never even see a memory address. C was used exclusively on UNIX and on mini-computers. Specification of data structure and operations is a must. High level languages:Procedural-Oriented language (3GL),Problem-Oriented language (4GL),Natural language … Machine code, one example of a low-level language, uses code that consists of just two numbers — 0 and 1. Programming Language • Pseudocodes: interpreters for assembly language • Fortran: the first higher level programming language • COBOL: he first business oriented language • Algol: one of the most influential programming languages ever designed • LISP: the first language … $.' A type system is a syntactic method for automatically checking the absence of certain erroneous behaviors by classifying program phrases according to the kinds of values they compute. In the machine language, a programmer only deals with a binary number. Assembly languages, that are thin wrappers over a corresponding machine language 3.
