The WC method is defined in Ruby to count the number of words and the number of lines

In Ruby we define a WC method that is used to count the number of lines of text, words, and characters that appear in a file, and the Ruby Code program is as follows:

def wc (filename)
   nline = nword = nchar = 0
   File.open (filename) do | io |
     io.each_line do | line |
       words = line.split (/ \ s + /). reject {| w | w.empty?}
       #In this example, the split method is used to split the word. When there are blank characters at the beginning of the line, the split method
       A blank string will be generated in the execution result, so we will delete the blank string.
       nline + = 1
       nword + = words.length
       nchar + = line.length
     end
   end
   puts "Number of lines in file: # {nline} \ nNumber of words in file: # {nword} \ nNumber of characters in file: # {nchar}"
end
wc ("sayGoodnight.rb")
# sayGoodnight.rb Here is just an example of the filename file. The files that follow can be changed.
