Thank you moritz.

Ya the code works fine but the problem is with the IDs which are not present in say two of the files. I want to print the value as 0. So if the file 1 and file 3 have an id present and its absent in 2 and 4. it should print

ID </t> value1 <\t> 0 <\t> value3 <\t> 0 <\n>.

The other thing is i want to know how can i iterate through files and make the hashes..??

sorry for the trouble
