Re^4: correspondence between two arrays

the thing is i want the results with respect to the entries in file1.txt and not the other way around. so if i make the second file as hash, then wont that make the prblem exactly opposite? as for the iteration, i am sorry i think i missed a bracket } there.. sorry for the mistake. Please tell me wat to do.

When you say you need to "check whether a value exists in something," that almost always means you should put something in a hash, and then check your values against that hash. Since you want to check whether values from file1 exist in file2, you put file2 in a hash (with the part you're checking against as the keys), and then start looping through file1 and checking its values to see if they exist as keys in the hash.
