Not a member of?

[ocprodigy]

Hi,

This is probably a VERY simple problem. Basically I've set a 2D structure:

struct IntegerCoordinate
{
	unsigned X;
	unsigned Y;
};

and then made a function class which has inherited from another class (which is all fine), with this bit of code:

// storage for the new vector class 
  vector<IntegerCoordinate> v;
  public:
	// constructor
	// functions
	void set_x(unsigned x) { v.X = x; }
	void set_y(unsigned y) { v.Y = y; }

But I'm producing the error

'X' : is not a member of 'std::vector<_Ty>'
1>          with
1>          [
1>              _Ty=IntegerCoordinate
1>          ]

Help would be appreciated, thank you!

In this code, v is a std::vector, which has no member x. But the vector is filled with objects which do have a member x.

Not entirely sure what your code is supposed to be but this set x of elements in the vector...

// storage for the new vector class 
  vector<IntegerCoordinate> v;
  public:
	// constructor
	// functions
	void set_x(unsigned x) { v[i++].X = x; }
	void set_y(unsigned y) { v[i++].Y = y;

v is a std::vector, not an IntegerCoordinate. What you want to do is set the x and y of a coordinate that is stored in the vector:

v[ 0 ].X = x;

Basically, what I'm trying to do is create a vector v filled with IntegerCoordinates.

But I'd like to be able to change the values of the IntegerCoordinates, and change them. So I'm assuming I've done this completely wrong...?
