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.


example:of array:

#include<stdio.h>
#include<conio.h>
void main()
{
int a[5];//only declare an array variable




example of structure:
struct book_bank
{
char title[5];
char author[3];
int pages;
float price;
};// this format of defining is also known as TEMPLATE
struct book_bank book1, book2;// declaration of variable
