It's a bad practice to use fflush(stdin) to flush the input stream.This method is UNPORTABLE, and hence should be avoided !
It will compile fine, but it's behavior is undefined on many C compilers.
But, it can be used safely with output stream.

To flush input stream, we can define something like :
Code: C
void my_fflush(FILE *pFile)
      char c;
      while( ((c = fgetc(pFile)) != EOF) && (c != '\n') );

and call it like :
Code: C
