As mentioned above, this is not a homework outsourcing service. show us what you've tried and we will point you in the right direction if we can
You need to write a program that will carry out the following steps.
- Get a file name from the command line, look at @ARGV in perlvar
- open 3 files, one to read from and two to write to.
- Read from the file supplied while there are lines in the file (perlsyn Loop control, while).
- split each line into individual characters
- For each character, if the character is alphabetic write it to the alpha file, if numeric to the numeric file, otherwise display an error (possibly with line and position of character). A simple regular expression perlrewould determine which action should be taken.
Have a look at the documentation linked above, try and code up the algorithm outlined and come back to us with specific Perl problems rather than a request to solve the entire problem.
Part of learning to code is learning a language and part of it is splitting up problems into sub-problems until each sub-problem can be written as a statement in the language you are using.
This is a discussion and education forum/community, mailing you a solution adds nothing to the community and offers an insufficient challenge to be worth doing for the satisfaction of solving by itself (perhaps try and get your end of term project written for you in under 160 chars and see if people will mail responses to you)
print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."
