Re: Input_file = ARGV.first

Show all headers | View raw

Oh ok, so for the question in the study drill --- "Write English comments for each line to understand what that line does." , what should I write beside the line Input_file = ARGV.first ?

I am trying to complete this exercise : http://learnrubythehardway.org/book/ex20.html

Thx ...
