Nesting of Structure in C

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

Program

#include<stdio.h>
struct DATE
{
int d;
int m;
int y;
};
struct stud
{
int rno;
char n[20];
struct DATE d1;
};
int main()
{
struct stud s1;
s1.rno=1;
strcpy(s.n,”LadderPython”);
s.d1.d=1;
s.d1.m=3;
s.d1.y=2010;
printf(“\nRollno=%d”,s1.rno);
printf(“\nName=%s”,s1.n);
printf(“\nDate=%d/%d/%d”,s.d1.d,s.d1.m,s.d1.year);
return(0);
}

Output

Rollno=1
Name=LadderPython
Date of Birth=1/3/2010

Description

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

Program

struct stud
{
int rno;
char n[20];
struct DATE
{
int d;
int m;
int y;
}d1;
};
int main()
{
struct stud s1;
s1.rno=1;
strcpy(s.n,”LadderPython”);
s.d1.d=1;
s.d1.m=3;
s.d1.y=2010;
printf(“\nRollno=%d”,s1.rno);
printf(“\nName=%s”,s1.n);
printf(“\nDate=%d/%d/%d”,s.d1.d,s.d1.m,s.d1.year);
return(0);
}

Output

Rollno=1
Name=LadderPython
Date of Birth=1/3/2010

Description

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