How to read user input from the command line in Go?

To read user input from the command line in Go, you can use the bufio package along with os.Stdin to create a new Scanner object. Then, you can use the Scan() method to read input from the user.

Here's an example of how you can read user input from the command line in Go:

package main

import (
	"bufio"
	"fmt"
	"os"
)

func main() {
	fmt.Print("Enter your name: ")

	scanner := bufio.NewScanner(os.Stdin)
	scanner.Scan()
	name := scanner.Text()

	fmt.Println("Hello, " + name + "!")
}

In this example, the fmt.Print function is used to display a prompt to the user. Then, we create a new Scanner object called scanner using bufio.NewScanner(os.Stdin). os.Stdin represents the standard input, which is the command line.

Next, we call the Scan() method on the scanner object to read the user's input. The scanner.Text() method retrieves the text that was scanned. We store the user's input in the name variable.

Finally, we display a welcome message to the user using the fmt.Println function.

When you run this program, it will prompt you to enter your name in the command line.
