Question

Use the aggregation (composition) concept to define and implement the class line(p1.x, p1.y, p2.x, p2.y) by using two points variables P1, and P2 of type point2D class defined in Q1. Beside the two points P1 and P2, the line class has the following functions: print(), MoveRel(Dx,Dy) (use the point2D’s MoveRel(Dx,Dy) function of the two points to achieve that), line(), line(x1,y1,x2,y2), line(P2D1,P2D2). * Your answer

Q3) Use the aggregation (composition)
concept to define and implement the class
line(p1.x, p1.y, p2.x, p2.y) by using two points
variables P1, and P2 of type point2D class
defined in Q1. Beside the two points P1 and
P2, the line class has the following
functions: print(), MoveRel(Dx,Dy) (use the
point2D's MoveRel(Dx,Dy) function of the
two points to achieve that), line(),
line(x1,y1,x2,y2), line(P2D1,P2D2). *
