About Flush the input buffer

[Laythe]

Greetings EveryOne

About Flush the input buffer in FAQ:

#include <stdio.h> 

int main(void)
{
  int   ch;
  char  buf[BUFSIZ];
  
  puts("Flushing input");
  
  while ((ch = getchar()) != '\n' && ch != EOF);
  
  printf ("Enter some text: ");
  
  if (fgets(buf, sizeof(buf), stdin))
  {
    printf ("You entered: %s", buf);
  }
  
  return 0;
}

is this where the input buffer get cleared?

while ((ch = getchar()) != '\n' && ch != EOF);

Thank You In Advance
