Dennis M. Ritche

 Dennis M. Ritche   --- Dennis M. Ritche was an American computer scientist he created the C programming language and, with long -time colleague Ken Thompson. In 1967, Ritchie began working at the Bell Labs Computing Sciences Research Center, and in 1968, he defended his PhD thesis on " Program Structure and Computational Complexity" at Harvard under the supervision of Patrick C, Fischer. However, Ritchie never officially received his PhD degree.

During the 1960's, Ritchie and Ken Thompson worked on the Multics operating system at Bell Labs. Thompson then found an old PDP-7 machine and developed his own application programs and operating system from scratch, aided by Ritchie and others. In 1970 , Brain Kernighan suggested the name "Unix"on the Multics". To supplement assembly language with a system- level programming language.Thompson  created B. Later, B was replaced by C. C created by Ritchie, who continued to contribute to the development of Unix and C for many years.

As we know, Ritchie is best known as the creator of the C programming language. a key developer of the Unix operating system, and co-author of the book"The Programming Language".he was the 'R' in K & R it is a common reference to the book;s authors kernighan and Ritchie. Ritchie worked together with Ken Thompson, who is credited with writing the original version of Unix, one of Ritchie's most important contributions to Unix was its porting to different machines and platforms,.They were so influential on Research Unix that Doug Mcllroy later wrote. "The names of Ritchie and Thompson may safely be assumed to be attached to almost everything not otherwise attributed.

Dennis M. Ritchie and Ken Thompson were awarded the Turing Award from the ACM in 1983, the Hamming Medal from the IFFE in 1990 and the National Medal of Technology from President Bill Clinton in 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007.

Cascading Style Sheet

Cascading Style Sheet (C.S.S.) Cascading Style Sheet – the cascading style sheet is a language for a webpage to style the webpage. The World Wide Web Consortium (w3C) created CSS. CSS describes how Html elements are to be displayed on the screen, on paper, or in other media. CSS saves a lot of work. It controls the layout of multiple WebPages all at once. CSS solved a big problem Html was never intended to contain tags for formatting a web page Html was created to describe the content of a web page like <h1> this is a heading</h> <p>this is a paragraph</p> When tags like<font> and color attributes were added to the html3.2 specification, It started a nightmare for web developers. Development of large websites, where fonts and color information were added to every single page, became a long and expensive process to solve this problem, The World Wide Web Consortium (w3C) created CSS. The CSS removed the style format from the Html page. There are two types of...

Computer Introduction The Nature have gifted human beings a powerful communication resource in the form of language to interchange ideas and communicate. Human being, using his excellent intelligence, developed computer, to manage and generate information, as per our requirements, in a systematic manner. Computer helps business organisation manage and allocate resources properly by aiding managers in decision-making process. managing an industry is almost as good as managing the information for control and decision making. Airlines and \Railway reservation system with database client-server architecture and real-time on -lie translation processing system has given us feel of betterment. In these days, our scientists is working on super quantum theory or method to developing a quantum computer also. The Quantum computing is the area of study focused on developing computer technology on the principles of quantum theory, which explains the nature and behavior of energy and...

Introduction of C ++ Language

Introduction of c++                 C++ is a semi-object-oriented programming language. It was developed by Bjarne Stroustrup at AT & T Bell Laboratories in Murray Hill, New Jersey, USA, in early 1983. C++ is a superset of C. Most of what we already know about c applies to c++ also. Therefore, almost all C programs are also C++ programs. However, there are a few minor differences that will prevent a C program to run under a C++ compiler. The most important facilities that C++ adds to C are classes, inheritance, function overloading, and operator overloading. These features enable the creation of abstract data types, inherit properties from existing data types, and support Polymorphism, thereby making c++ a truly semi-object-oriented language.  The object-oriented features in C++ allow programmers to build large programs with clarity, extensibility, and ease of maintenance, incorporating the spirit and efficiency of C. the additio...
