Nested Structure

As you know though structure we can process data record by record that is why structure is called user defined data type. In some specific case you nested structure where a structure is inside of a structure. For example when process a student record with their dob. Take a look on following example.

#include<stdio.h>

#include<conio.h>

#include<string.h>

typedef struct s

{

    int roll;

    char name[10];

    struct d

    {

         int dd,mm,yy;

    }dob;

}student;

void main()

{

    student stu;

    clrscr();

    stu.roll=101;

    strcpy(stu.name,"Sona");

    stu.dob.dd=15;

    stu.dob.mm=5;

    stu.dob.yy=1995;

    printf("\n\nStudent Detail\n\n");

    printf("Roll\t%d",stu.roll);

    printf("\nName\t%s",stu.name);

    printf("\nDate of Birth %d/%d/%d",stu.dob.dd,stu.dob.mm,stu.dob.yy);

    getch();

}
