ostringstream

[James Madison]

How do I purge an ostringstream object?

I put some strings into it, but I want to print it, purge it, and put different strings in it, print it, etc.

How do I do that without using a pointer and new/delete?

Load an empty string "" into it:

ostringstream out;
...
out.str("");

os.rdbuf()->seekpos(0,ios:ut);

Note: an open mode argument which determines position of the put pointer.
