Step by Step solution about How to resolve the algorithm Guess the number/With feedback step by step in the Go programming language

This Go program implements a number guessing game. The program first generates a random integer between 1 and 100 using the rand.Intn function. It then prompts the user to guess the number and stores the user's guess in the variable guess. The program then compares the user's guess to the randomly generated number and prints a message to the user indicating whether the guess is too low, too high, or correct. If the guess is correct, the program prints a congratulatory message and exits. If the guess is incorrect, the program prompts the user to guess again. The program continues to loop until the user guesses the correct number.

package main

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

const lower, upper = 1, 100

func main() {
    fmt.Printf("Guess integer number from %d to %d: ", lower, upper)
    rand.Seed(time.Now().Unix())
    n := rand.Intn(upper-lower+1) + lower
    for guess := n; ; {
        switch _, err := fmt.Scan(&guess); {
        case err != nil:
            fmt.Println("\n", err, "So, bye.")
            return
        case guess < n:
            fmt.Print("Too low. Try again: ")
        case guess > n:
            fmt.Print("Too high. Try again: ")
        default:
            fmt.Println("Well guessed!")
            return
        }
    }
}
