Bizarre issue!!!

[stevegreen22]

Hey guys.

Can someone perhaps help explain this issue I'm having?

Essentially I get an error whenever I add an endl or a out stream to another.

For example:

      cout << ac.getSizeOfCollection();

Works fine but....

      cout << ac.getSizeOfCollection() << " Size" <<endl;

Doesn't

I have the same issue with this:

            cout << "fdsddigifg " << meh.getNumberOfTracks();
//

Works fine but the one below doesn't

            cout << "fdsddigifg " << meh.getNumberOfTracks() <<" Tracks"<<endl;
//

Any ideas or suggestions? I've tried to trace back the outstream as it's overloaded and every step of the way it's fine. I simply don't understand it. -.-

Try if std::endl makes a difference. Because std::endl is the end of line marker, and endl could be anything. If you added a variable "int endl;" at the beginning of a function that would produce some rather funny results. BTW. Once your programs get larger, you will very much prefer std::cout to cout because it provides a lot more information when you read code.

Odds are 'meh.getNumberOfTracks()' is not returning an 'stream&' so there is no stream for 'endl' to do it's thing against.

'meh.getNumberOfTracks()' doesn't need to return a stream&.
'cout << "fdsddigifg " << meh.getNumberOfTracks()' should return a stream&.
'meh.getNumberOfTracks()' should return a nonnegative integer.

You're correct! Which is why one should never respond under the effect of pain.

Thanks for catching that.

We don't have enough info. meh.GetNumberOfTracks()... What does it return? Did you write the operator<< method to handle this? How about ac.getSizeOfCollection? Can you output ANYTHING after one of these? Is the problem just endl? What is the problem? A compiler error? What is it? A runtime error? Incorrect results?
