    The file source.txt contains "Be my friend". fseek(fs, 0, SEEK_END); moves the file pointer to the end of the file. fseek(fs, -3L, SEEK_CUR); moves the file pointer backward by 3 characters. fgets(c, 5, fs); read the file from the current position of the file pointer. Hence, it contains the last 3 characters of "Be my friend". Therefore, it prints "end".
