C is a programming language developed in 1972 by Dennis Ritchie at AT&T's Bell Laboratories, known for its reliability, simplicity, and portability. It is widely used in operating systems and gaming frameworks, supporting structured programming and modular code for maintainability. The name 'C' was derived from its predecessor 'B', with the language evolving from features of earlier programming languages.

2. Introduction to C Language
What is C?
• C is a programming language developed at AT & T’s
Bell Laboratories of USA in 1972.
• It was designed and written by Dennis Ritchie.
• It is reliable, simple and easy to use.
• C is highly portable, software written in on
computer can be run on another computer
• An important feature of C is its ability to extend
itself.
• C program is basically a collection of functions.

3. • Major parts of popular operating systems like
Windows, UNIX, Linux are still written in C.
• Many popular gaming frameworks have been built
using C language.
• C is a structured programming language.
• C supports functions that enables easy maintainability
of code, by breaking large file into smaller modules.
• Comments in C provides easy readability.
• C is a powerful language.

4. Historical Development of C

5. Why Name 'C' was given to this language?
• Many of the ideas of C language were derived
and taken from 'B' language.
• BCPL and CPL are previous versions of 'B'
language.
• As many features came from B it was named
as 'C'.

6. Getting Started With C
Steps in learning C language:
Step 1: Know about alphabets, numbers and special
symbols used in C
Step 2: Using step 1 constructed constants, variables
and keywords
Step 3: write instructions using step 2
Step 4: Combining step 3 form a program
