Sorry, i guess i want. clear enough. vector template is defined like this:
template <class T, size_t N>
class vector;
Where T is arbitrary type (supposedly arithmetic, or it woult be meaningless otherwise) and N is an amount of components in a vector (aka vector dimension or size) and not an amount of dimensions in an array (vector is a one dimensional array of elements). So vector is statically sized, and parameters passed to constructor are values to be stored in it and not sizes of corresponding array dimensions.
