XOR swap: Swaping the values of 2 variables.This tip submitted by John Rambo on 2013-02-03 17:45:25. It has been viewed 6568 times.Rating of 6.6 with 20 votes I am not going to be explaining how XOR works, so I suggest you google "C bitwise operators" and learn about them. In a tutorial I found, it states this: \" ^ The bitwise-exclusive-OR operator compares each bit of its first operand to the corresponding bit of its second operand. If one bit is 0 and the other bit is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.\" Here's the code: /* This is a XOR swap. It works by using the XOR bitwise operator to compare variable values. */ #include More tips Help your fellow programmers! Add a tip! |
