Sometimes a template class is defined to have only parameter and no
type (e.g. class something) information. Like the below sample. My
question is, why define template class in this way (e.g. I can
implement in an alternative way to put the parameter into
constructor)?

For example:

template <size_t sz>
class FixedArray {
int a[sz];
public:
// Allows running STL algorithms over fixed array
int* begin();
int* end();
};

Try doing this with a parameter passed to constructor, without a heap
allocation.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
