Introduction to C

🔹 What is C?

C is a structured, procedural programming language developed in the early 1970s by Dennis Ritchie at Bell Labs. It was designed to write operating systems and is known for its efficiency, portability, and close interaction with hardware.

🔹 History of C

C was developed in 1972 by Dennis Ritchie at Bell Laboratories (AT&T). It was originally created to develop the UNIX operating system, which was initially written in assembly language. C provided a more portable and efficient way to write low-level system software while retaining high-level language features.
It evolved from earlier languages such as B and BCPL. Over the decades, C has become one of the most widely used programming languages in the world and is the foundation of many modern languages like C++, Java, and Pytho

🔹 Key Features of C

• 🔧 Low-level memory access with pointer support

• 💨 Fast and efficient execution

• 🔁 Rich set of operators and built-in functions

• ⚙️ Modular programming with functions

• 💻 Highly portable across platforms

• 🧱 Foundation for many modern languages (C++, Java, Python)

🔹 Why Learn C?

• Builds a strong base in programming logic

• Essential for system-level and embedded development

• Widely used in operating systems, compilers, and hardware drivers

• Enhances understanding of how computers work internally

🔹 Applications of C

• Operating system kernels (e.g., Linux)

• Embedded and firmware programming

• Compilers and interpreters

• Database engines and system tools

• Game development and real-time systems
