WebEnter the first variable: 4 Enter the second variable: 2 The value of a after swapping: 2 The value of b after swapping: 4 Here, a new es6 feature, called destructuring assignment [a, b] = [b, a] , is used to swap the value of two variables. Web//Logic for swapping the two numbers without using any extra variable a = a + b; b = a - b; a = a - b; The logic involved here is that, similar to every other programming language, the variables in C++ stores the most recent value stored into it.
WebAug 21, 2013 · Surely you want the XOR swap algorithm? At least for numeric variables. Conventional swapping requires the use of a temporary storage variable. Using the XOR swap algorithm, however, no temporary storage is needed. The algorithm is as follows: X := X XOR Y . Y := X XOR Y. X := X XOR Y WebTo perform swapping in above example, three variables are used. The contents of the first variable is copied into the temp variable. Then, the contents of second variable is copied to the first variable. Finally, the contents of the temp variable is copied back to the second variable which completes the swapping process.
WebThe computer actually has an implicit “temp” variable that stores intermediate results before writing them back to a register. For example, if you add 3 to a register (in machine-language pseudocode): ADD 3 A // add 3 to register A The ALU (Arithmetic Logic Unit) is actually what executes the instruction 3+A. It takes the inputs (3,A) and ...
