in [Ruby]
|
From: Francisco Martinez on 4 Aug 2010 04:14 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= . -- Posted via http://www.ruby-forum.com/.

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