Passing an array as an argument in golang

You have defined your function to accept a slice as an argument, while you’re trying to pass an array in the call to that function. There are two ways you could address this:

1. Create a slice out of the array when calling the function. Changing the call like this should be enough:

   nameReader(a[:])
   

2. Alter the function signature to take an array instead of a slice. For instance:

   func nameReader(array [3]name) {
       ...
   }
   

   Downsides of this solution are that the function can now only accept an array of length 3, and a copy of the array will be made when calling it.
