The vector class (or rather the vector *template*) that comes with the 
standard library is useful for holding a dynamical number of entries. For a 
simple 3d vector use an array as in C - or if you want to do it 
object-orientated write a Vector class around it. 

As example the class I have written for my raytracer for that purpose:
