fflush() does NOT clear the input buffer.  That it does so under
Borland, et. al. is an example of these compilers' noncompliance with
the ANSI standard.  There are a number of ways to handle this sort of
problem:

1) Use gets(), or the safer fgets(), for all input, and read the results
from the string instead of directly from stdin.  Replace all calls to
scanf() with gets()/sscanf(); replace all calls to getchar() with
gets(), etc.
2) Clear the input buffer in an ANSI-safe way, such as "while (
getchar() != '\n' ) ;", after each function that leaves characters in
the buffer.
3) Read your input from the console using conio functions.
