    If you do not close or flush the output file, the file is often not saved.

    > printf("%f",SeatF[i][j]);
    %f prints floats, not ints.

    > printf("\n");
    Now, are you trying to print all the seats for one all on the same line?
    Or just every seat on a line by itself?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
