Start your programming journey with one of the most powerful and foundational languages — C. This comprehensive course is designed for absolute beginners as well as intermediate learners who want to build a solid understanding of programming using the C language. Whether you're preparing for college-level programming, cracking technical interviews, or planning to explore systems or embedded development, this course covers everything step-by-step. Through hands-on examples, real-world practice problems, and structured explanations, you’ll learn how to write clean and efficient C code — from your first printf() to advanced data structures and memory management.
Before writing your first C program, you need a simple environment to write, compile, and run code. Don’t worry — it’s easy and free! This chapter walks you through setup on Windows, macOS, Linux, and even online options.
C:\MinGW\bin to Environment VariablesMost Linux distros already have GCC installed. If not:
sudo apt update sudo apt install build-essential
Now use any editor like nano, gedit, or VS Code and run your programs with:
gcc myprogram.c -o myprogram ./myprogram
xcode-select --install
If you don’t want to install anything yet, try writing and running C code online:
Soon at UdaanPath.com, we’ll provide a fully integrated online C compiler so you can write and test code right on our platform!
In the next chapter, we’ll write your first C program — the classic Hello, World! — and understand how to compile and run it on your system.
