Hi,
I am new to Ruby and come form C language.
Can someone pint out for me my mistake please.
It seem not to find the file ever no regardless of the path.

class Scan
  attr_reader :filename, :alpha_count, :digit_count,
:non_printable_count, :line_count, :word_count, :symbol_count
  attr_writer :filename, :alpha_count, :digit_count,
:non_printable_count, :line_count, :word_count, :symbol_count
  filed_ptr=0

  def initialize(filename)
    @filename=filename
    @alpha_count=0
    @digit_count=0
    @symbol_count=0
    @non_printable_count=0
    @blank_count=0
    @line_count=0
    @word_count=0
  end #initialize

  def open_count
      printf( "filenamae= %s\n",@filename)

  file_ptr=File.open(@filename,"r") do |file|
      file.each_byte do |ch|
        case ch.to_i
        when 32
          @blank +=1
        when 0..31
          @non_printtable_count+=1
        when 48..57
          @digit_count +=1
        when 65..90 ,97..122
          @alpha_count +=1
        when -1
          puts "Found End of file"
        else  @symbol_count +=1
        end #case
      end #each_byte
      file_ptr.close
    end #open
  end #open_count
end #class

print "Enter the path and file name ej. /home/user1/file.txt  :->"
fname=gets
ff=Scan.new(fname)
ff.open_count()
