Please provide me the code how to compare two file . Suppose there are 3 file.We compare file1 with file2 line by line(Row wise). Suppose i compare logonid(unique) of file1 with file2. If logonid is match then copy the entire row to file3. Please tell me the what is the code for it.
How about you post the code you have tried so far in a compilable format which demonstrates the problems you are experiencing and then we will take a look and help if we can.
No one here is going to write this for you.

stop posting the same message over and over again, maggot
start with some basic algorithm
open file streams
while ( eof of file1 && eof of file2) {
stringvariable1 = read a line from file1 (figure out how to do it)
stringvariable2 = read a line from file2 (--do--)
boolean = compare stringvariable1,stringvariable 2 ( how?)
if (boolean) //true
then write stringvariable1(or 2) to file3
else
print "no matching lines found"
}
close filestreams
