+===== description of strrchr =====
+strrchr () is a string function that finds the last occurrence of a character in a string. As a result, the pointer comes to this character or the null pointer if this character is not found.
+In the following example, a string is read by fgets. fgets hangs at the end of a New-line character (\ n). We are looking for a pointer to this character and replace it with a '\ 0' characters.
