OUTPUT:

enter number of points:5

Enter x-part of point:1
Enter y-part of point:2

Enter x-part of point:2
Enter y-part of point:1

Enter x-part of point:5
Enter y-part of point:-1

Enter x-part of point:1
Enter y-part of point:-5

Enter x-part of point:2
Enter y-part of point:-6

Distance for point 1=21.476471
Distance for point 2=18.102528
Distance for point 3=20.093359
Distance for point 4=20.153830
Distance for point 5=22.307423

C.O.G=(2,1)
Maximum distance from C.O.G.=7.000000
