Nope. Maybe a warning.

This is a pre-increment rather than post-increment, so you start
with 1 rather than 0. Not wrong. If you wanted to use i++ you'd
have to start with i =3D 1.

ng

The characters are just reproduced in the printed string. Not wrong.

Yup. that's what they are looking for. argv[] is an array of
pointers to char.

Not an error. C89 says it will return an unspecified value. C99 says
it will return 0, but it will return. May not generate a warning.
