Nested Structure in C
In C language, we can create nested Structure (Structure within Structure). There are two ways to define a nested structure.
- By separate structure
- By Embedded structure
- Separate structure
strcut Dob{
int date;
char month[20];
int year;
}
struct student{
int id;
char nm[30];
struct Dob doj;
}std1;
- Embedded structure:
struct student
{
int id;
char name[20];
struct Dob
{
int data;
char month[20];
int year;
}doj;
}std1;
Example
Write a program of Nested structure in C language.
#include <stdio.h>
struct student{
int id;
char ename[20];
struct date
{
int date;
int month;
int year;
}doj;
}
std = {101,"Mohan",{22,6,1990}};
int main(int argc, char *argv[]){
printf("\nEmployee SSN : %d",std.id);
printf("\nEmployee Name : %s",std.ename);
printf("\nEmployee DOJ :%d/%d/%d",std.doj.date,std.doj.month,std.doj.year);
return 0;
}
Output
Employee SSN : 101 Employee Name : Mohan Employee DOJ :22/6/1990
