can anyone tell me what is this error?

[Srija]

can u post the code or about what the program belongs to???????

i will get this error when my code is like this.. anyway thanks for spending your time to take a look at my code.

[coder777]

You forgot to implement the destructor (like the errors says)

[Nisheeth]

[code]This[/code] becomes This

[xNutty]

erm im kinda new to c++... cause i self learn c++ myself through the web.. mine explaining to me what is destructor and how should i edit my code to make it no error?

thanks in advance

[coder777]

class LocationData {
public:
LocationData();
LocationData(string, int, int, float, float);

// LocationData(const LocationData& orig);
virtual ~LocationData(); // This is the destructor

...

};

Implementation:

LocationData::~LocationData() {
}

The destructor is called automatically before the according object is destroyed (delete/out of scope)

{
  LocationData ld
  ...
  // do some stuff with ld
  ...
} // here ~LocationData() is called 

[xNutty]

omg.. thanks for your help....
