C Programming Tutorial – Introduction

C programming is a foundational and widely used programming language in computer science and engineering. This C programming tutorial is designed for beginners and engineering students to learn C from basics to advanced concepts. C is often called the mother of programming languages because many modern languages are built on its principles.

What is C Programming?

C programming is a general-purpose, procedural programming language that provides low-level access to memory and high-level constructs for structured programming.

History of C Programming

The C programming language was developed by Dennis Ritchie in the early 1970s at Bell Laboratories (USA). It was created as an evolution of the B language and became the foundation for UNIX operating systems. It was created as an improvement over an older language called B (developed by Ken Thompson). C quickly became popular because it was efficient, flexible, and allowed programmers to interact closely with computer hardware.

Why Learn C Programming?

• Builds strong programming fundamentals
• Used in operating systems and embedded systems
• Foundation for C++, Java, and Python
• Improves problem-solving and logic

Features of C Programming Language

• Simple and efficient
• Portable across platforms
• Structured and modular
• Fast execution
• Direct memory access using pointers

How C Programming Works

C is a compiled language. Source code is processed, compiled, assembled, linked, and executed as a machine-level program.
