I would like to read standard input from the command line, but my attempts have ended with the program exiting before I\'m prompted for input. I\'m looking for the equivalen
Can also be done like this:-
package main
import "fmt"
func main(){
var myname string
fmt.Scanf("%s", &myname)
fmt.Println("Hello", myname)
}
Another way to read multiple inputs within a loop which can handle an input with spaces:
package main
import (
"fmt"
"bufio"
"os"
)
func main() {
scanner := bufio.NewScanner(os.Stdin)
var text string
for text != "q" { // break the loop if text == "q"
fmt.Print("Enter your text: ")
scanner.Scan()
text = scanner.Text()
if text != "q" {
fmt.Println("Your text was: ", text)
}
}
}
Output:
Enter your text: Hello world!
Your text was: Hello world!
Enter your text: Go is awesome!
Your text was: Go is awesome!
Enter your text: q
Try this code:-
var input string
func main() {
fmt.Print("Enter Your Name=")
fmt.Scanf("%s",&input)
fmt.Println("Hello "+input)
}
In my case, program was not waiting because I was using watcher
command to auto run the program. Manually running the program go run main.go
resulted in "Enter text" and eventually printing to console.
fmt.Print("Enter text: ")
var input string
fmt.Scanln(&input)
fmt.Print(input)
I'm not sure what's wrong with the block
reader := bufio.NewReader(os.Stdin)
fmt.Print("Enter text: ")
text, _ := reader.ReadString('\n')
fmt.Println(text)
As it works on my machine. However, for the next block you need a pointer to the variables you're assigning the input to. Try replacing fmt.Scanln(text2)
with fmt.Scanln(&text2)
. Don't use Sscanln
, because it parses a string already in memory instead of from stdin. If you want to do something like what you were trying to do, replace it with fmt.Scanf("%s", &ln)
If this still doesn't work, your culprit might be some weird system settings or a buggy IDE.
