I know that the Sieve of Eratosthenes is a fast way to find all prime
numbers in a given range.
I noticed that one implementation of a sieve spends a lot of time
marking multiples of small primes as composite. For example, it takes
1000 times as long to mark off all of the multiples of five as it
t
Yes, this is a good solution. In implementing this it is important to
take care that a ray which passes through a vertex counts as
intersecting the polygon exactly once.

the ray cuts the polygon at several places on both sides of the point.
if the no off cuts @ both side is odd
point lie inside the polygon
else outside the polygon.
Plz see the example in the attached PDF.

The actual size is system dependent because the language doesn't
specify the size of int or long int.
I'll assuming the common convention that sizeof(int)=4 and sizeof(long
int)=8.
The size of a union is the size of the largest element in the union.
So sizeof(D) = 5*sizeof(int)=20
C and B will be t
what will be the size of union A ,B,C and D. also please explain the logic.
* union A{*
* long int y[5];*
* union B{*
*double g;*
*union C{*
* int k;*
* union D{*

Find the number of intersections for a ray passing from the exterior of the
polygon to the point needed.
If odd, the point lies inside the polygon.
If even, the point lies outside the polygon.
