Changing the program to work with files

[Alex Mr]

Hi every body

I have a program that is working with Console ( input - output)

I wanted to see if anybody can help me to modify it so that it takes its
input from a file (text) and write its output also to a file (binary)

because I am new to Ruby and I dunnot working with files .

Thank you very much

Google for "the Ruby book" - the free introductory book by the Pragmatic
Programmers.

All introductory language tutorials cover file handling - usually in a much
better way than a newsgroup ever could...

which difference with file i/o and stdio that confuse you?

Hi, Thank you for reply .

May I ask you to help me modify the program to take input form files
instead of Console ?

Can you please modify it for me ? if yes, Can I send the program to you
to do this favor for me ?

When I Google for "ruby book", the very first hit is this:

Programming Ruby: The Pragmatic Programmer's Guide
http://www.ruby-doc.org/docs/ProgrammingRuby/

The chapter "Basic Input and Output" is here:

http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_io.html

It says things like this:

aFile = File.new("testfile", "r")
# ... process the file
aFile.close

You can change the "r" to a "w" to read the file.

Does that help?

Use the builtin File class.

Just change ARGV values with variables from file. This example do the work
for 3 params taking them from command or file.

var1=3D ARGV[0]
var2=3D ARGV[1]
var3=3D ARGV[2]

file =3D 'where_is_the_file_with_param'

file_with_param =3DFile.new(file,"r")
param =3D file_with_param.gets.split(' ',-1)
file_with_param.close()

var1 ||=3D param[0]
var2 ||=3D param[1]
var3 ||=3D param[2]

Use the builtin File class.
