節錄： 

typedef struct
{
    std :: string latitude;
    std :: string longitude;
} coordinate;

coordinate is typedef on anonymous struct, not object. You should create object of coordinate in your function, or not use typedef, i.e.

struct coord
{
    std :: string latitude;
    std :: string longitude;
} coordinate;

now, coordinate is object. And one question, why you type spaces after std and after ::? It's legal, but strange.
