I never used the delaunay triangulation so I don't know if there is anything special with it. But, in the general case, if you want to modify a point, you could do something like that:
point[i] = Point_2(point[i].x() + 1, point[i].y())
if you wanted for instance to translate the point of 1 unit on the x-axis.

Thanks for the response.Actually this code was just an example of what I'm going to do.Because I want to make a delaunay triangulation, I must use an array(vector) of points, but later I want to manipulate the x and y of each point of the vector, how can I access them? in the case of one point it's: point.x() and point.y(), what about an array of points?
You have to use the copy constructor like this:points[0] = Point_2(1.0, 1.0);

I'm new to CGAL.I'm a little bit confused about using vector of points in CGAL.how can I have access to x and y elements of Point_2, I mean :typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel; typedef Kernel::Point_2 Point_2; typedef std::vector<Point_2> Vector; Vector points; points.reserve(5); int main(){ points[0].x() =1.0; points[0].y() =1.0; return 0;}
points[i].x() or points[i].x produces error.thanksParisa
