未定义GoLang按位异或

Question

So I just started learning GoLang. I'm trying to perform a bitwise operation XOR between two byte (uint8) numbers. Every time I run the command "go vet" I get the following error:

undefined: xˆy

My code:

package main

import (
    "fmt"
    "math"
)

func main() {
     var x byte = 1
     var y byte = 2

     fmt.Println("XOR x and y =", xˆy)    
}

Answer 1

You are using the wrong character.

Don't use ˆ. Use ^.

package main

import (
    "fmt"
)

func main() {
    var x byte = 1
    var y byte = 2

    fmt.Println("XOR x and y =", x^y)
}

Output:

XOR x and y = 3
