Answer 1

Yes they are important because you can give input to your programs through files and even store the output in file by creating a new file like a text file.

THE ADVANTAGE IS: when you close your program all memory is cleared so output is not available.But if output is stored in file it's anytime available.

Answer 2

yeah this are necessary when you decide to create a file in C
