symmetric encryption is not working

   I have been using gpg (GnuPG) 2.1.18 on a debian linux
for several years.  In the last few days, I have noticed
that symmetric encryption is not working.

The command

gpg -c --cipher-algo AES testfile

creates testfile.gpg after asking for a passphrase.

However, the command

gpg testfile.gpg yields the message

> gpg: WARNING: no command supplied.  Trying to guess what you mean ...
> gpg: AES encrypted data
> gpg: encrypted with 1 passphrase

and creates a plaintext file without asking for
a passphrase.
