This is an easy one. Not sure, if you have done anything till now. But here is the algorithm for you to start:

1. Read file A into array
2. Read File B into array
3. Compare array A and Array B. Add unique values to Array C
4. Write Array C to a text file.

Once you've written code and have a code specific question, feel free to ask.
