    I have a class

    class Point2D {

    double x[2];

    public:
    ....

    }

    I want to implement a function that can take in as input point2Dsort( double * pdA, int number_of_points) and sort it in lexicographic order. (i.e. if p1.x() > p2.x() then p1 > p2 ...

    Is there a way to define operator< on the point class and implement point2Dsort using c++ sort() function?

    Thanks,
    --j
