Compound data type: Difference between revisions

It is also possible to add a constructor (this allows the use of <tt>Point(x, y)</tt> in expressions):

struct Point

{

int x;

int y;

Point(int ax, int ay): x(ax), y(ax) {}

};

Point can also be parametrized on the coordinate type:

template<typename Coordinate> struct point

{

Coordinate x, y;

};

// A point with integer coordinates

Point<int> point1 = { 3, 5 };

// a point with floating point coordinates

Point<float> point2 = { 1.7, 3.6 };

Of course, a constructor can be added in this case as well.
