How to use the XOR operator in Golang? Let’s learn together!

The exclusive OR (XOR) operation is a common binary operator, which is often used in computer science for encryption and verification. In Golang, the XOR operator is represented by the symbol ^ and can be used to perform bit-level operations. This article will introduce the use of the XOR operator in Golang and provide some specific code examples to help readers better understand.

In Golang, the XOR operator ^ can be used for XOR operations on integers, bytes and bits. First, let's start with the XOR operation on integers.

1. XOR operation of integers
   XOR operation of integers refers to performing XOR operation on each binary bit of two integers. The exclusive OR operator ^ compares the binary bits of the two operands. If the values ​​of the corresponding bits are the same, the result is 0; if the values ​​of the corresponding bits are different, the result is 1.

Here is a sample code that shows how to XOR two integers using the XOR operator ^:

package main

import "fmt"

func main() {
    a := 5
    b := 3
    result := a ^ b
    fmt.Println(result) // 输出2
}

In the above code, we define two The integers a and b are assigned the values ​​5 and 3 respectively. Then, we use the XOR operator ^ to XOR a and b and assign the result to the variable result. Finally, we use the fmt.Println function to output the value of result, which is 2.

2. XOR operation of bytes
   The XOR operation of bytes has the same principle as the XOR operation of integers, which is to perform XOR operation on each binary bit of the byte.

Here is a sample code that shows how to XOR two bytes using the XOR operator ^:

package main

import "fmt"

func main() {
    a := byte(0x55)
    b := byte(0xAA)
    result := a ^ b
    fmt.Printf("%X
", result) // 输出FF
}

In the above code, we define two Bytes a and b are assigned values ​​of 0x55 and 0xAA respectively. Then, we use the XOR operator ^ to XOR a and b and assign the result to the variable result. Finally, we use the fmt.Printf function to output the hexadecimal representation of the result, which is FF.

3. bit XOR operation
   bit XOR operation is to perform XOR operation on the corresponding bits of two numbers. In Golang, you can convert integers to binary strings for better understanding of bitwise XOR operations.

Here is a sample code that shows how to XOR the bits of two integers using the XOR operator ^:

package main

import (
    "fmt"
    "strconv"
)

func xorBits(a, b int) {
    binaryA := strconv.FormatInt(int64(a), 2)
    binaryB := strconv.FormatInt(int64(b), 2)
    
    fmt.Printf("a   = %04s
", binaryA)
    fmt.Printf("b   = %04s
", binaryB)
    fmt.Println("--------------")
    
    result := a ^ b
    binaryResult := strconv.FormatInt(int64(result), 2)
    fmt.Printf("a^b = %04s
", binaryResult)
}

func main() {
    xorBits(10, 7)
}

In the above code, we define A function xorBits that accepts two integers a and b as parameters. In the function, we convert a and b into binary strings by calling the strconv.FormatInt function. Then, we use the XOR operator ^ to perform a bitwise XOR operation on a and b and assign the result to the variable result. Finally, we call the strconv.FormatInt function again to convert the result to a binary string and use the fmt.Printf function to output the result.

Through the above example code, we can see the bit operation rules corresponding to the bit XOR operation. At each bit of the binary system, if the values ​​on the corresponding bits are the same, the result is 0; if the values ​​on the corresponding bits are different, the result is 1.

Through the above code examples and explanations, I believe readers will have a better understanding of the use of XOR operators in Golang. The XOR operation is an important operator in computer science and can play an important role in encryption, encoding and verification. I hope this article will be helpful to readers, let us learn and explore the power of Golang together!
