أخي الكريم, السلام عليكم و مرحبا بك في المنتدى.

أخي موضوعك مخالف, نرجو منك قراءة قواعد المشاركة, سأقوم بتغيير عنوان الموضوع و لكن أرجوك ان تنتبه للقواعد في المرات القادمة.

بالنسبة للسؤال, فنظام الوندوز يستخدم "\r\n" في الملفات من أجل اضافة سطور جديدة, بينما في اللينكس يستخدم "\n" فقط من أجل الفصل بين السطور.

مثلا,

fprintf(result,"\nResult of Function 18:\n");

حولها إلى:

fprintf(result,"\r\nResult of Function 18:\r\n");

Software applications and operating systems usually represent the newline with one or two control characters:

Systems based on ASCII or a compatible character set use either LF (Line Feed, 0x0A) or CR (Carriage Return, 0x0D) individually, or CR followed by LF (CR+LF, 0x0D 0x0A). 
LF:    Unix and Unix-like systems, Xenix, Mac OS X, BeOS, Amiga, RISC OS and others 
CR+LF: CP/M, MP/M, DOS, Microsoft Windows 
CR:    Apple II family and Mac OS through version 9
