Introduction to C Programming

C is a general-purpose programming language.

C is known for its efficiency and control. C uses a structured approach, supports low-level memory manipulation, and offers a rich set of built-in operators and functions.

History Of C

Developed by Dennis Ritchie at Bell Labs in the early 1970s.
Known for its efficiency, simplicity, and low-level system access.
Follows a procedural programming paradigm.
Focuses on functions and structured programming.
Highly portable language, allowing programs written in C to run on different platforms with minimal modifications.
C uses a syntax that includes variables, data types, operators, and control structures (loops and conditionals).

Features Of C

Installation Of C

To run C/C++ in your system you need two things:

MinGW compiler: Search for “mingw compiler downloader” in Google, install it, and set the environment variable by giving the compiler path.
Code Editor/IDE: Download VS Code. (Avoid DevC++/Turbo C as they are discontinued.)
Create a file in your editor with a .c extension.
Install Code Runner Plugin in VS Code to easily run code in the IDE, or use the terminal for manual compilation.
