What I am  trying to do is concatenate multiple strings together and store it in another string variable to use later. Below is my latest attempt at my problem.   I am new to C++ strings, so any help is appreciated.  Thanks for your time.

--Charly
string output << "Printing '" << fieldText[9] << "' using '" << printerName << "' on " << someDate << endl;
 
cout << output << endl;

Change 'string' to 'ostringstream'.

Then if you later need to access it as a string (for example, to assign it to a string variable), call output.str().
ostringstream output;
output << "Printing '" << fieldText[9] << "' using '" << printerName << "' on " << someDate << endl;
cout << output << endl;

Thanks for the bump in the right direction.  I ended up using an ostringstream to get what I wanted.  Thanks again.

--Charly
ostringstream os;
os << "Printing '" << fieldText[9] << "' using '" << printerName << "' on " << someDate << endl;
std::string output(os.str());
cout << output;

Heh, that's what I get for not refreshing the page...

So I don't need to explicitly convert it to a string first then?  Awesome.  Thanks for the help you two.
