In this tutorial, I’ll be teaching you how to swap two numbers without using a third or temporary variable. This is a common technique that can be applied in any programming language, but in this video, I’ll demonstrate how to do it using the C programming language. In this video, you will learn how to swap two numbers using basic arithmetic operations like + and -. I’ll walk you through the concept of swapping variables without using extra memory, and show you how to implement this technique in a simple C program. I’ll also cover how to prompt the user for input, display the results before and after the swap, and test the program with different inputs. The tutorial begins with setting up the C program and declaring the necessary variables. Then, we dive into performing the swap using three simple operations: A = A + B, B = A - B, and A = A - B. This algorithm allows us to swap the values of two variables without requiring any additional storage. Afterward, we move on to prompting the user for input, executing the swap, and displaying the output both before and after the operation. Once the code is written and tested, I’ll demonstrate how the program works using different values to show how the swapping takes place in action. If you’re new to programming or want to improve your C skills, this tutorial will teach you an important concept that you can apply in many scenarios. Whether you're learning C for school, work, or just for fun, this method of swapping values is an efficient and elegant solution.
