Hello,

I am still learning ruby. My question is, often we see things like this:

   def set_miles(miles)
     @miles = miles
   end

Here, we're defining a custom method set_miles , then passing it an 
argument (what's the reason of doing so?), then we're setting the 
instance variable @miles to a local variable miles, why's that for? I 
know I can use attr_accessor but things like this occurs in various 
place. What's the point of doing this?


I know I sound funny but i can't understand. Any help would be much much 
much appreciated.
