Why is there an error in the output (golang)?

Question

go

Wrote this code:

package main
import (
  "fmt"
)

func main () {
  x := 123
  fmt.Printf ("Hello %v", x)
}

For some reason, we output with a percentage at the end:
> Hello 123%

Question: why is there a percentage at the end and how to fix it?

Answer 1

It doesn't output %
% - it's most likely that yours already outputs it.
Add the newline code "\n" to the end like this fmt.Printf ("Hello %v\n", x)and it will be what you want
