Answer 1

package main

import (
    "fmt"
    "math/rand"
    "time"
)

func generateHex(length int) string {
    hexChars := "0123456789ABCDEF"
    result := make([]byte, length)

    for i := 0; i < length; i++ {
        index := rand.Intn(16) // Random number between 0 and 15
        result[i] = hexChars[index]
    }

    return string(result)
}

func main() {
    rand.Seed(time.Now().UnixNano()) // Seed the random number generator

    length := 8
    hexNumber := generateHex(length)

    fmt.Println("Random Hexadecimal Number:", hexNumber)
}
