Hi, I have a problem, I have to write a method using an array but I’m  
not able to combine the two things.  
I have a txt file which contains words and puntuaction symbols separated  
whit spaces.  
I have to write a method which receives the txt file as a first entry  
argument and returns an array of tokens. I have to call the methos and  
print IN THE SCREEN all the tokens contained in the array the array in  
this way:

token 1= the  
token 2= house  
token 3= is  
token 4= big  
token 5= .

Take a look at the File#read and File#readline methods, and to  
separate in tokens: String#split or String#scan.

StringScanner (in the stdlib) is intended for tasks like this. They show  
an  
example at the start.
