[vtk-developers] unsigned/signed comparison

[David Doria]

Is the preferred way to do this comparison:
for(unsigned int i = 0; i < polygon2->GetNumberOfPoints(); i++)

to use a signed int for the counter:
for(int i = 0; i < polygon2->GetNumberOfPoints(); i++)

or cast the compare value as an unsigned int:
for(unsigned int i = 0; i < static_cast<unsigned
int>(polygon2->GetNumberOfPoints()); i++)

Thanks,

David
