OUPS sorry it's in french it means Multiple choice question.

I hope nobody helps you so you can learn what the consequences are of being lazy and expecting something out of it. By not helping you, I and everyone else are doing you a favor.

Looks like you misunderstood me, i'm not asking for someone that would make that project from me ,and i know how to use google and to keep trying till i learn something .
What i want is ask some questions that might be helpful through the way .

You had posted your code here, now it's gone...
You were not able to write to a file because you were not closing the writer, so all the data was probably just staying in the internal buffer.
After writing to the file you should close it.

Yep that's why i've actually deleted the post . I figured out i didn't close it.
Thanks for your reply .
I got a new question while going with this i figured out that while writing to a txt \n doesn't work, after googling it i found that i should use \r\n instead .
Any idea why ? and what does the \r do ?

'\n' is called a 'Line feed' symbol
'\r' is called a 'Carriage return' symbol
Unix based systems use '\n' as the newline character while Windows/DOS use '\r\n' as the newline character.

'\n' jumps to new a new line while '\r' returns to the start of the line

There's a colossal difference between him wanting to cheat on a project at his university and me wanting help with a hobby of mine.
