Swap Two Variables Using XOR - GeeksforGeeks In this article, we will learn how to swap two variables using the XOR technique Example: The XOR operator returns true if the number of true inputs is odd To swap two variables using XOR in C++, wc can do it byBy performing the XOR operation on the two variables three times, we can swap their values without using a third variable
How does XOR variable swapping work? - Stack Overflow Here’s a neat programming trick to swap two values without needing a temp: x = x xor y y = x xor y x = x xor y More details in Swap two variables using XOR On line 1 we combine x and y (using XOR) to get this “hybrid” and we store it back in x XOR is a great way to save information, because you can remove it by doing an XOR again On
C program to swap two numbers using bitwise XOR operation In this tutorial, we will learn how to swap two numbers in C using bitwise XOR operation Let’s take a look at the program : firstNumber = firstNumber ^ secondNumber; secondNumber = firstNumber ^ secondNumber;
Swap two numbers using bitwise operator in C++ - CodeSpeedy We are going to use a bitwise XOR operator in C++ to swap two numbers in this tutorial Let us first have a quick look at the working of this method with an example Suppose we have a number 23 stored in variable x
XOR Swap | Baeldung on Computer Science The most common use of XOR is to swap two variables without any auxiliary storage: algorithm SwapUsingXOR(a, b): INPUT a, b = Two variables to be swapped OUTPUT a and b swap their values using XOR operation Swap using the XOR bit operation a <- a XOR b b <- b XOR a a <- a XOR b
Approach to Swapping Two Numbers Using XOR (an interesting . . . The XOR swap is an efficient way to swap two numbers without needing extra space for a temporary variable It is particularly useful in low-level programming and situations where memory usage is critical
