operator overloading

nglwthnati2de (7)
Ok so I am pretty new to programming and as you will see It does not agree with me too well. I have written this code that is supposed to ooutput the information to a console but I keep getting this error about no operator found which takes a right-hand operand of type 'RacingData'. I know what the problem is: I never defined the operator<< that would take RacingData as a parameter. I was told to fix it with something along these lines

ostream& operator<<(ostream& os, RacingData& data) {
   // Do whatever you need to print 'data' to 'os'. For example:
   os << data.getName() << endl;

    return os;
}
but when I do that, I get like 5 other errors. So my question is how do I implement this into my code so that it will work propeerly?

The function should be deined as:
 
 
ostream& operator<<(ostream& os, const RacingData& data)


That aside, what are the other errors? If you're not specific, we can't help.
