Golang: Access struct fields

• Use a dot operator.

Access fields of a struct pointer

1. Use a dot operator. The pointers are automatically dereferenced.
2. Parenthesize the struct pointer and then use a dot to access fields.

If we don’t parenthesize the struct pointer, it will show invalid indirection error. Because Go thought the field we tried to access should be a pointer.
