I try to write a program that reads a file with two fields.The first field is a
costumer ID and the second is the costumer name by using " ! " as a seperator between
2 fields. Store costumer ID as the key and the costumer name as value into a hash.
My code is below, I have a problem that $info{ $key} does not show the value. What is
the problem ? How to change it? Thank you.
***** myfile.pl ***** $filename ="costumer.txt"; open(FILE,$filename ) or die ("can
not open file : $filename"); while ($line = <FILE>) { ($id,$name) =
split(/!/,$line,2); $info{$id} = $name; } print "Enter id:"; $key = <STDIN>; print
("ID: $key NAME : $info{ $key} \n");
