Nesting of Structure in C

Defining one structure within another structure. is known as nesting of structure. We can do it as follows:

Program to demonstrate nesting of structure.

#include<string.h>
#include<stdio.h>
struct dob
{
int day;
int month;
int year;
};
struct student
{
int rollno;
char name[20];
struct dob d;
};
int main()
{
struct student s;
s.rollno=131;
strcpy(s.name,”Lovejot”);
s.d.day=11;
s.d.month=7;
s.d.year=2007;
printf(“\nRollno=%d”,s.rollno);
printf(“\nName=%s”,s.name);
printf(“\nDate of Birth=%d/%d/%d”,s.d.day,s.d.month,s.d.year);
return(0);
}

Output

Rollno=131
Name=Lovejot
Date of Birth=11/7/2007

Description

In the above program, variable d of structure dob has been declared inside the structure student.

Program to demonstrate nesting of structure.

#include<string.h>
#include<stdio.h>
struct student
{
int rollno;
char name[20];
struct dob
{
int day;
int month;
int year;
}d;
};
int main()
{
struct student s;
s.rollno=131;
strcpy(s.name,”Lovejot”);
s.d.day=11;
s.d.month=7;
s.d.year=2007;
printf(“\nRollno=%d”,s.rollno);
printf(“\nName=%s”,s.name);
printf(“\nDate of Birth=%d/%d/%d”,s.d.day,s.d.month,s.d.year);
return(0);
}

Output

Rollno=131
Name=Lovejot
Date of Birth=11/7/2007

Description

In the above program, structure dob has been defined inside the structure student hence implementing nesting of structure.
