The title of your question is      How to join a slice of strings into a single string    but in fact  reg is not a slice  but a length-three array       string is just syntactic sugar for  in this case   3 string   To get an actual slice  you should write   reg      string   a   b   c      Try it out  https   play golang org p vqU5VtDilJ    Incidentally  if you ever really do need to join an array of strings into a single string  you can get a slice from the array by adding      like so   fmt Println strings Join reg              Try it out  https   play golang org p zy8KyC8OTuJ

Use a slice  not an arrray  Just create it using  reg      string   a   b   c     An alternative would have been to convert your array to a slice when joining    fmt Println strings Join reg            Read the Go blog about the differences between slices and arrays
