Are you sure that Structure is object oriented, because
structs came from C, and C wasn't an object-oriented
program, and C++ was using it at the beginning where now
they use class for the same function which is better

Array is a collection of a fixed number of components all of
the same type: it is a homogeneous data structure.

structs (records) - we use them to group items of different
types; a collection of a fixed number of components in which
the components are accessed by name. The components as
mention can be of different types. A struct is typically
heterogeneous.
