cin.ignore(numeric_limits<streamsize>::max(), '\n');

Ignore everything until a newline

Obviously you've read the documentation (i.e., you're not an idiot).

So what part don't you understand?

Here is a topic I recently posted, it was about stream object and not cin. hopefully this can help you understand it better.
