I am writing a program to input data from a file, format it and then output to another file. For some reason when i make the file I get this error:

----jGRASP exec: make

g++ -ggdb -c Billionaire.cpp
iostream:39:0,
                 from Billionaire.cpp:7:
c:\mingw\lib\gcc\mingw32\4.8.1\include\c++\ostream: In constructor 'Billionaire::Billionaire()':
ostream:384:7: error: 'std::basic_ostream<_CharT, _Traits>::basic_ostream() [with _CharT = char; _Traits = std::char_traits<char>]' is protected

       ^
Billionaire.cpp:13:26: error: within this context

                          ^
makefile:4: recipe for target 'Billionaire.o' failed
make: *** [Billionaire.o] Error 1

 ----jGRASP wedge2: exit code for process is 2.
 ----jGRASP: operation complete.

Can anyone shed some light on thei error? I don't understand why the constructor is prducing an error with the ostream.

My code:

ifstream and ofstream cannot be members of a class like you have them. It's probably better to just have inData() and outData() declare ifstream/ofstrem, open the file, then read/write.

void Billionaire::outData()
{
    ofstream outFile("filename.txt");
    //The output data is formatted accordingly
    outFile
        << setw(12) << "Name: " << getName() << endl
        << setw(17) << "Rank: " << getRank()
        << setw(12) << "Worth:" << left << setw(8) << getWorth() << right

Thank you. I honeslty didn't even notice I declared them in the header file. Just needed another pair of eyes.
