C Programming Language Step by Step Part 1
1 like558 views
This document provides an overview of the C programming language. It discusses the history and development of C, starting with predecessors like ALGOL-60 and BCPL in the 1960s and 1970s. C was created in the early 1970s and the first C compiler was released in 1978. Since then, C has become widely used for system programming and is foundational to many other languages like C++ and Java. The document outlines some key advantages of C, like its efficiency and ability to handle low-level tasks. It also provides brief descriptions of common C programming concepts.

- 6. What is Assembly Language? Each personal computer has a microprocessor that manages the computer's arithmetical, logical, and control activities. Each family of processors has its own set of instructions for handling various operations such as getting input from keyboard, displaying information on screen and performing various other jobs. These set of instructions are called 'machine language instructions'. A processor understands only machine language instructions, which are strings of 1's and 0's. However, machine language is too obscure and complex for using in software development. So, the low-level assembly language is designed for a specific family of processors that represents various instructions in symbolic code and a more understandable form. By Rumman Ansari
- 7. Advantages of Assembly Language Having an understanding of assembly language makes one aware of − How programs interface with OS, processor, and BIOS; How data is represented in memory and other external devices; How the processor accesses and executes instruction; How instructions access and process data; How a program accesses external devices. Other advantages of using assembly language are − It requires less memory and execution time; It allows hardware-specific complex jobs in an easier way; It is suitable for time-critical jobs; It is most suitable for writing interrupt service routines and other memory resident programs.

- 10. By Rumman Ansari C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972. In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard. The UNIX operating system, the C compiler, and essentially all UNIX applications programs have been written in C. The C has now become a widely used professional language for various reasons. 1. Easy to learn 2. Structured language 3. It produces efficient programs. 4. It can handle low-level activities. 5. It can be compiled on a variety of computer platforms.
- 11. By Rumman Ansari Facts about C C was invented to write an operating system called UNIX. C is a successor of B language which was introduced around 1970 The language was formalized in 1988 by the American National Standard Institute (ANSI). The UNIX OS was totally written in C by 1973. Today C is the most widely used and popular System Programming Language. Most of the state-of-the-art softwares have been implemented using C. Today's most popular Linux OS and RBDMS MySQL have been written in C.
- 12. By Rumman Ansari Why to use C? C was initially used for system development work, in particular the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as code written in assembly language. Some examples of the use of C might be: Operating Systems Language Compilers Assemblers Text Editors Print Spoolers Network Drivers Modern Programs Databases Language Interpreters Utilities
