🎙️ Introduction
Hello everyone!
Welcome to Chapter 2 – History of C Programming Language.
In this chapter, we will learn how the C language was created, who developed it, and why it became one of the most important...Read More
🕰️ Early Days of Programming Languages
In the early days of computers (1950s–1960s), programming was done using:
Machine Language (0s and 1s)
Assembly Language
These languages were:
Very difficult to learn
Machine dependent
Time-consuming to write and debug...Read More
🧬 Birth of BCPL and B Language
🔹 BCPL (Basic Combined Programming Language)
Developed by Martin Richards in 1967
Used mainly for system programming
Simple but not very powerful
🔹 B Language
Developed by Ken Thompson in 1970
Derived from BCPL
Used for early UNIX operating systems
Had limitations like:
No data types
Poor performance on newer ...Read More
👨💻 Development of C Language
The C programming language was developed by:
⭐ Dennis Ritchie
Year: 1972
Place: Bell Laboratories (USA)
Dennis Ritchie created C by improving the B language and...Read More
🖥️ C and UNIX Operating System
One of the biggest milestones in C’s history:
The UNIX operating system was rewritten in C
Before C, operating systems were written in assembly ...Read More
📈 Standardization of C Language
As C became popular, different versions appeared.
To avoid confusion, standardization was introduced.
🔸 K&R C (1978)
Written by Kernighan and Ritchie
First official book on C
Called “The C Programming Language”
🔸 ANSI C (C89 / C90)
Standardized by ANSI in 1989
Ensured portability and...Read More
🌍 Why C Language Became So Popular
C became popular because it is:
Fast and efficient
Close to hardware
Portable (runs on many systems)
Powerful for system programming
Foundation for many languages like...Read More
🔗 Modern Use of C Language
Even today, C is used in:
Operating Systems (Linux, Windows parts)
Embedded Systems
Microcontrollers
Game engines Compilers and interpreters...Read More
✅ Summary
Let’s quickly revise:
C was developed by Dennis Ritchie in 1972
It evolved from BCPL → B → C
C played a major role in UNIX
It became standardized as ANSI...Read More
