Hello,
I try to make this exercise :
Exercise 76: A programmer has chosen to represent locations as Cartesian
points or just points:
;Location is one of:
;--Posn
;--Number
;interp. Posn are positions on the Cartesian grid,
;Numbers are positions on the number line
Design the function in-reach, which determines whether or not a given
location's distance to the origin is strictly less than some constantR.
So I must design a function called in-reach.
Am I right I need to use two structs (Posn) . One for the given location
and one for the origon ?
Regards,
Roelof
