However, this is bad code.
Use cin.get() or cin.getline() instead of cin>> if you don't know
how many times you are gonna read. |

or characters.
You seem to have lots of questions on istream. Why don't you just
read through the document for once? It only takes 15 minutes and
it would save lot of your time on these questions.
what?
