* Memory (array size) is fixed
* Accessing an element in array takes constant time. E.g. -
5th element in an array can be accessed as array i.e.
searching/accessing an element in array takes comparatively
less time than in structures.
* Adding/deleting an element in the array is comparatively
difficult since the data already present in the array needs
to be moved
* Memory (structure size) can be changed dynamically
* Accessing an element in a list takes more time
comparatively since we need to traverse thro the list
* Adding/deleting takes less time than in arrays
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
An array behaves like a built-in data type. All we have to
do is to declare an array variable and use it. But in the
case of a structure, first we have to design and declare a
data structure before the variables of that type are
declared and used
Both arrays and structures are classified as structured data
type as provide a mechanism that enables us to access and
manipulate data in relatively easy manner. but they differ
in number of ways:-
1)An array is a collection of related data elements of same
type. Structure can have elements of different types.
2. An array is derived data type whereas a structure is a
programmer defined one.
3) An array behaves like a built in data types only we need
to declare it.but in case of structures , first we have to
design and declare a data structure before the variables of
that type are declared and used.
int a;//only declare an array variable
example of structure:
};// this format of defining is also known as TEMPLATE
struct book_bank book1, book2;// declaration of variable
