Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.
Q: I am studying English and I want to know the main difference between 'Have you got?' and 'Do you have?' questions. Are they the same? Is one more formal than the other?.
A: 
Contrary to the above, 'Have you got' is more common in British English than 'Do you have' (about 2:1); but 'Do you have' is much more common in American English than 'Have you got' (more than 10:1). Note that the response includes only the relevant auxiliary: - 'Do you have a pen'; 'Yes, I do'. - 'Have you got a pen'; 'Yes, I have'. In fact, the most common form where I live (in Northern Ireland) is simply 'Have you', but that sounds old-fashioned to many English speakers elsewhere.
