Reading from “standard input” is really useful if you are making a command-line application and require user input.
package main
import (
"bufio"
"os"
"fmt"
)
func main() {
reader := bufio.NewReader(os.Stdin)
s, _ := reader.ReadString('\n')
fmt.Printf(s)
}
First setup a new bufio reader, then use ReadString function, with a default wait character, which we have set to a newline (\n).
The application will pause at this point and wait for user input before proceeding.
