If we look purely at your program, the first error I see is that you have
failed to check the return value of scanf.

If you read the documentation on scanf, you'll see something similar to what my
manpage says:

These functions return the number of input items successfully matched and
assigned, which can be fewer than provided for,  or  even zero in the event of
an early matching failure.

If you do check the return value then you can have a real understanding the
input that the program receives.
