C is a general-purpose, procedural programming language developed in the early 1970s by Dennis Ritchie at Bell Labs. It is known for its simplicity, speed, and efficiency, making it one of the most widely used programming languages in system/software development.
Structured language: Supports functions and modular programming.
Low-level access to memory: Using pointers, C allows direct memory manipulation.
Fast execution: Compiled code is highly efficient.
Portability: C programs can run on different machines with minimal or no modification.
Rich library support: Comes with a standard library for I/O, string handling, math, etc.
Operating systems (e.g., parts of UNIX, Linux)
Embedded systems
Compilers and interpreters
Device drivers
Game development
C programming is often considered the foundation for learning other programming languages like C++, Java, and Python.
Job after learning C :
Embedded Systems Developer – Write code for IoT and hardware devices.
Firmware Engineer – Develop software for microcontrollers.
Systems Programmer – Work on operating systems and low-level tools.
Software Developer (C/C++) – Build performance-critical apps.
Kernel Developer – Contribute to OS kernels like Linux.
