The document provides an introduction to the C programming language, detailing its history, development at Bell Laboratories, and its derivation from the B language. It highlights the establishment of the ANSI C standard in 1988 and outlines the structure of a simple 'hello world' program demonstrating basic programming concepts including installation, compilation, and execution. The document serves as a basic guide for beginners to understand C programming fundamentals.

1. Programming in C
and
Data Structures

2. Introduction to C
C – Language History
C language is a structure oriented programming language,
was developed at Bell Laboratories in 1972 by Dennis Ritchie
C language features were derived from earlier language called “B” (Basic
Combined Programming Language – BCPL)
C language was invented for implementing UNIX operating system
In 1978, Dennis Ritchie and Brian Kernighan published the first edition “The C
Programming Language” and commonly known as K&R C
In 1983, the American National Standards Institute (ANSI) established a
committee to provide a modern, comprehensive definition of C. The resulting
definition, the ANSI standard, or “ANSI C”, was completed late 1988.

3. Basic Program
We are going to learn a simple “Hello World” C program in this section. Also, all the below topics are explained
in this section which are the basics of a C program.
 1. C basic program with output and explanation
 2. Steps to write C programs and get the output
 3. Creation, Compilation and Execution of a C program
 How to install C compiler and IDE
 4. Basic structure of a C program
C Basic Program:
#include <stdio.h>
int main()
{
/* Our first simple C basic program */
printf("Hello World! ");
getch();
return 0;
}
Output: Hello World!
