+/* ==============================================================
+Good practice: Feel free to use the following predefined macros
+__FILE__ : stands for the name (string %s) of the current file
+__LINE__ : stands for the line number (integer %d) where it executes
+__func__ : stands for the name of the function in whose body it is placed (string %s)
+__DATE__ : stands for the date when the file was compiled last time (string %s)
+__TIME__ : stands for the time when the file was compiled last time (string %s)
+__STDC__ : stands for 1 is standard compiler implementation was used , or 0 if a non standard compiler was used (integer %d)
