How Structures are initialized?

How Structures are initialized? 

A structure can be initialized at design time as follows:

Example :

struct student

{

int roll_no;

int age;

char name[20];

};

struct student stu = {1,17,"Mukesh"};

What are nested structures?

A structure built within another structure is called as nested structure.

Example : 

struct dob

{

int day;

int month;

int year;

};

struct student

{

int roll_no;

char name[20];

struct dob date; // structure with in a structure

}stu;

What is meant by an array of structures?

An array of structures contains data elements of every structure variable stored in to an array.

Example : 

struct student

{

int reg no;

int age;

char name[20];

}stu[10];
