A Brief Guide on C Programming Language.

A BRIEF GUIDE ON C PROGRAMMING LANGUAGE Introduction to C C is probably the most widely known programming language. It is used as the reference language for computer science courses all over the world, and it's probably the language that people learn the most in school along with Python and Java. Source: www.freecodecamp.org About C Programming Procedural Language - Instructions in a C program are executed step by step. Portable - You can move C programs from one platform to another and run it without any or minimal changes. Source: www.programiz.com About C Programming cont. Speed - C programming is faster than most programming languages like Java, Python, etc. General Purpose - C programming can be used to develop operating systems, embedded systems, databases, and so on. Source: www.programiz.com Why Learn C Programming? C helps you to understand the internal architecture of a computer, how computer stores and retrieves information. After learning C, it will be much easier to learn other programming languages like Java, Python, etc. Source: www.programiz.com History of C language C language has evolved from three different structured language ALGOL, BCPL and B Language. In 1988, the language was formalised by American National Standard Institute(ANSI). In 1990, a version of C language was approved by the International Standard Organisation(ISO) and that version of C is also referred to as C89. Source: www.programiz.com Facts about C C was invented to write an operating system called UNIX. C is a successor of B language which was introduced around the early 1970s. The language was formalized in 1988 by the American National Standard Institute (ANSI). Source: www. tutorialspoint.com Facts about C cont. The UNIX OS was totally written in C. Today C is the most widely used and popular System Programming Language. Most of the state-of-the-art software have been implemented using C. Today's most popular Linux OS and RDBMS MySQL have been written in C. Source: www. tutorialspoint.com C Programs A C program can vary from 3 lines to millions of lines, and it should be written into one or more text files with extension ".c“. For example, hello.c. You can use "vi", "vim" or any other text editor to write your C program into a file. Source: www. tutorialspoint.com Local Environment Setup If you want to set up your environment for C programming language, you need the following two software tools available on your computer, (a) Text Editor and (b) The C Compiler. Source: www. tutorialspoint.com The C Compiler The source code written in source file is the human readable source for your program. It needs to be "compiled", into machine language so that your CPU can execute the program as per the instructions given. Source: www. tutorialspoint.com
