Suppose i have a polygon with 5 points. They are constant.
I use "gotoxy()" to define the point positions.
Something like this:
x1=30; y1=10; gotoxy(x1,y1); cout<<"A"; x2=50; y2=10; gotoxy(x2,y2); cout<<"B"; //.....and so one up five
Now i should to give a another point (X,Y), and calculate with wich point defined early is too near.
For the first i thinkd that i cand substract X from earch point x1, x2....x5 and Y from y1, y2... y5 and to see the almost points, or who have less difference between coordinate. But i wrong.
How cand i do this? Some ideas please!
