How To Swap Two Numbers Using C Program Without Using a Temporary Variable!

Welcome to Code_Directive 👨‍💻✨ In this video, we will learn how to swap two numbers in C programming using the powerful bitwise XOR operator. This is one of the most famous interview questions and is heavily used in low-level programming, embedded systems, memory optimization tasks and competitive coding. Instead of using a third variable or temporary storage, we perform swapping purely using bit manipulation. This tutorial explains the logic in a simple and beginner-friendly way, so even if you are new to C language or bitwise operations, you will clearly understand how XOR works internally and how it can be used to swap values efficiently. We will go through code line by line, understand how XOR toggles bits, and analyse what exactly happens during each step of execution. Make sure to watch this video till the end because these small tricks help in competitive exams, interviews, embedded development, microcontroller coding, and algorithm optimization. 💡 What You’ll Learn : How to swap two integers without using a temporary variable How XOR (^) operator works in C Bitwise manipulation and internal bit toggling logic Why XOR swap is popular in competitive programming & interviews Practical usage of bitwise operators in low-level computing 🧠 Topics Covered in this C Program : Bitwise XOR operator Variable swapping techniques Low-level integer representation stdio.h library usage Optimization mindset in C programming 👉 Perfect for beginners, college students, and interview preparation. 👍 Like & Share if this helped you 🔔 Subscribe to Code_Directive for more C programming tutorials 💬 Comment below for any doubts or topic requests Thank You
