$ echo "A 1 2 3 4" | go run test.go
entire: A
next field: A
I need to read several lines from standard input that are like "A 1 2 3 4" (code does one line for now) and something goes wrong. Scanln
should read the entire line and Fields
should split it by newlines? Why does Scanln read only one word?
package main
import (
"fmt"
"strings"
)
func main() {
var line string
fmt.Scanln(&line)
fmt.Println("entire: ",line)
for _,x := range strings.Fields(line) {
fmt.Println("next field: ",x)
}
}
$ echo "A 1 2 3 4" | go run test.go
entire: A
next field: A
