Please use code tags when posting to this site - find the '<>' button, select all your code and press it.

Your problem is partly the '/>' you have at the end of your operator== function (doing XML half way through?) and also the fact that operator== isn't allowed to access the private variables of your class. Either add it as a friend to your class or add the function to your class, either way.

could u please write for me what should i change? am confused u explain but if u can write the code it is better .

You need to change the implementation of the operator== function to match the prototype declaration. This is the prototype:

bool operator ==(const Car &) const;

your implementation:

bool operator ==(Car A,Car B)/>

should look like this:

bool Car::operator ==(const Car & B) const

And leave off both of these 'A.' in if(A.reportingMark =B.reportingMark && A.carNumber = B.carNumber)

Also, you should be using double equals, since you are comparing, not assigning.
