How to convert istringstream object to string and char array?

Question

I have this object:

istringstream ob_stream;

I need to convert this object to string and char array for work. How to do?

`ob_stream.str()` returns an `std::string`, and you can invoke `c_str()` on the returned `std::string` — Andy Prowl, Apr 06 '13 at 22:17
and how to do for object istream...example istream is_object; I need also convert to string and char array... — user1779502, Apr 06 '13 at 22:25
Make sure you create a separate string if you store the result of `c_str()`. — chris, Apr 06 '13 at 22:25
@user1779502, An `istream` contains no string until you read one. — chris, Apr 06 '13 at 22:25

For a std::string:

ob_stream.str();

for a char array:

ob_stream.str().c_str();
