How to set nth Bit of a Number using C Program

Описание: Welcome to Code_Directive 👨‍💻✨

In this video, you’ll learn how to set the nth bit of a number in C programming using bitwise operators — one of the most fundamental yet powerful concepts in low-level programming.
We’ll explore how the left shift and bitwise OR (|) operators can be combined to turn ON a specific bit in any number. This concept is essential in embedded systems, hardware programming, IoT, and even competitive coding.
By the end of this tutorial, you’ll clearly understand how bit manipulation works, how to set a bit without affecting others, and how to display the results before and after modification.
Perfect for beginners, students, and C programming enthusiasts who want to master the logic behind bits and bytes.
