void my_point::moveNE(int n1, int n2)
//
//
{
n1=xCoord;
n2=ycoord;



}

trying to figure out void moveNE. is intended to move point object in the north-east direction by adding n1 to the x-coord and adding n2 to y-coord of th e point . it is assumed that the value of n1 and n2 are both greater than zero. for example if my_point object p1 is (10,10) then p1.moveNE(1,2) should make the coodinates of p1 as (11,12)

Why not just add n1 to the yCoord and n2 to the xCoord?
