Question

I’m writing c++ project, which contains several classes. I created .h file named Position.h, with one array and one function:

class Position
{
public:
    Coord positions[25];

public:
    void setPos(int index, double x, double y)
    {
        positions[index].x = x;
        positions[index].y = y;
    }
};

I want to set values in this array from another classes, so every class in this project will see the same values.
I included “Position.h” in other classes, but i can’t access the “positions” array.

Anyone can help me plz??

Answer 1

Just chnage the statement :

Coord positions[25]; 

to

static Coord positions[25]; 

also change void setPos
to

static void setPos

while accesing the array ,access it as:

Position::positions[any value]

But before accessing the array,make sure you call the function setPos
