1 Answer

Answer :

Declaration of structure:-

struct structure_name

{

data_type member 1;

data_type member 2;

.

.

.

data_type member n;

} structure variable 1, structure variable 2,..., structure variable n;

Example:-

struct student

{

int rollno;

char name[10];

}s1;

Initialization:-

struct student s={1,"abc"};

structure variable contains two members as rollno and name. the above example initializes rollno to 1 and name to "abc".

Program:-

#include<stdio.h>

#include<conio.h>

struct college

{

int collegeid;

char collegename[20];

};

struct student

{

int rollno;

char studentname[10];

struct college c;

};

void main()

{

struct student s={1,"ABC",123,"Polytechnic"};

clrscr();

printf("\n Roll number=%d",s.rollno);

printf("\n Student Name=%s",s.studentname);

printf("\n College id=%d",s.c.collegeid);

printf("\n College name=%s",s.c.collegename);

getch();

}
