Is it necessary to end every row with a null character…is it optional and what happens if we dont do it
Ending of the row
Hey @vector.9974 it is necessary to end every row with null character, because null character acts as a full stop to a statement. If you won’t have any full stop in a paragraph, then how would you know when to stop and then when to start reading other line. If you won’t add null character at the end of your row then you will get the garbage value at the end if every row which if not handled cautiously will lead to wrong output.
