Answer 1

You cannot fseek line by line, because you do not know how long the lines are until you read them.

You should either read the whole file into a list of lines, or if the file is too big for that and you only need the last lines, read fixed-sized chunks from the end of the file and implement a bit more complicated logic which detects lines from such data.
