Nested Structure in C Language
Categories: C language
C provides us the feature of nesting one structure within another structure by using which, complex data types are created. For example, we may need to store the address of an entity employee in a structure. The attribute address may also have the subparts as street number, city, state, and pin code. Hence, to store the address of the employee, we need to store the address of the employee into a separate structure and nest the structure address into the structure employee. Consider the following program.
#include<stdio.h>
struct address
{
char city[20];
int pin;
char phone[14];
};
struct employee
{
char name[20];
struct address add;
};
void main ()
{
struct employee emp;
printf("Enter employee information?\n");
scanf("%s %s %d %s",emp.name,emp.add.city, &emp.add.pin, emp.add.phone);
printf("Printing the employee information....\n");
printf("name: %s\nCity: %s\nPincode: %d\nPhone: %s",emp.name,emp.add.city,emp.add.pin,emp.add.phone);
}
Output
Enter employee information?
Arun
Delhi
110001
1234567890
Printing the employee information....
name: Arun
City: Delhi
Pincode: 110001
Phone: 1234567890
The structure can be nested in the following ways.
1. By separate structure
2. By Embedded structure
