How to read/write from/to file using Go?

Question

I\'ve been trying to learn Go on my own, but I\'ve been stumped on trying read from and write to ordinary files.

I can get as far as inFile, _ := os.Open(INFIL

Try this:

package main

import (
  "io"; 
  )


func main() {
  contents,_ := io.ReadFile("filename");
  println(string(contents));
  io.WriteFile("filename", contents, 0644);
}
