text editing commands error

I dont know why but text editing commands doesnt work they just seem on the fprintf screen

Answer 1

In your fprintf call, the escape characters require a ‘backslash’ or ‘backslant’, not a ‘forward slash’ or ‘forward slant’.

To do a carriage return and linefeed, use \n, do not use /n.
