Suppose some class contains slice (dynamic array) as data member.
Constructor takes integer value that defines the size of data
should be allocated. After object was constructed size of slice
never changes by design.
Dynamic arrays are allocated with extra space that we can know
from 'capacity' property. But how can I allocate exactly as much
elements as I want? Because in case described above we don't need
extra space.
I know it's possible to use malloc in constructor and free in
destructor. But what if I want to expose inner slice by shallow
copy (i.e. by copying pointer and size, but not underlined data)
then use it just like usual dynamic array whose lifetime does not
depend on lifetime of an object it belongs and is managed by GC?
