Answering "Have you got" questions with "I do"

Solution 1:

EDIT: Since the OP changed the tense in his question, I have updated my answer:

1. Yes, I have.

   or

   Yes, I have got some ice cream.

2. No, I haven't.

   or

   No, I haven't got any ice cream.

Solution 2:

For the question "Have you got any ice cream?" which is correct:

Yes I do

Yes I have

The traditional answer would be "yes I have" but "yes I do" is common in American usage and is gaining usage in the UK too.

Solution 3:

Arguably both are correct:

'Have you got any ice-cream?'

'Yes, I have got ice-cream.' -OR- 'Yes, I do have ice-cream.'

In Australia both "I do" and "I have" are used and essentially mean the same thing.

It is the same for the negative forms:

'No, I have not got ice-cream.' -OR- 'No, I do not have ice-cream.'
