File Compare
Write a program that opens two text files and reads their contentsinto two separate
queues. The program should then determine whether the files areidentical by comparing
the characters in the queues. When two nonidentical characters areencountered,
the program should display a message indicating that the files arenot the same. If both
queues contain the same set of characters, a message should bedisplayed indicating
that the files are identical.
