Thanks for the feedback.
About gets() .. my compile doesn't compile if I use it so I had to learn to use fgets() instead. I thought the error was coming from there which is why I tried to use __fpurge (I've used it with getchar() successfully).

getchar
FGETC(3) Linux Programmer's Manual FGETC(3)
NAME
fgetc, fgets, getc, getchar, ungetc - input of characters and strings
SYNOPSIS
#include <stdio.h>
int fgetc(FILE *stream);
char *fgets(char *s, int size, FILE *stream);
int getc(FILE *stream);
int getchar(void);
int ungetc(int c, FILE *stream);
DESCRIPTION
fgetc() reads the next character from stream and returns it as an unsigned char cast to an int, or EOF on end of file or error.
getc() is equivalent to fgetc() except that it may be implemented as a macro which evaluates stream more than once.
getchar() is equivalent to getc(stdin).
fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an
EOF or a newline. If a newline is read, it is stored into the buffer. A terminating null byte ('
