Will we be expected to sanitise or validate the input file? For example, if the input file requests the next page for process 9 (obviously doesn't exist), should we print an error? Or perhaps shoudl we catch any potential invalid inputs and skip them?

I think this is meant to be a simple project. So, I don't think input sanitization is necessary, but it is good practice.

So, if any process request comes other than 0 to 3 in the input string, I am skipping that process and processing rest of the processes as required without printing any error

If you countered a number outside of 0-3 then you would assume the file is corrupted and you shouldn't continue reading. So best practice is to print an error message then call exit(EXIT_FAILURE).

Actually the best practice is to never call "exit" because it doesn't end the program "gracefully". The best practice is to return EXIT_FAILURE (1) in main. If you are interested.
