Structure:

• Structure is the derived data type.
• Structure is the collection of multiple data elements that can be of different data types.

Syntax:

Struct structure_name{
    data_type variable_name;
    data_type variable_name;
    -
    -
}
Example:
struct employee {
    int code;
struct {
char fn[20];
char ln[20];
}
name;
float sal;
struct {
int date, month, year;
}
DOJ;
};

Program:

#include<stdio.h>
#include<conio.h>
struct employee{
int code;

struct{
char fn[20];
char ln[20];
}
name;
float sal;
struct{
int date, month, year;
}
DOJ;
};
int main(){
    struct employee e[100];
    int i, n;
    printf("Enter number of employees:");
    scanf("%d", &n);
    for(i=0; i<n; i++)  {
        printf("\nEnter Code:");
        scanf("%d", &e[i].code);
        printf("\nEnter First Name:");
        gets(e[i].name.fn);     
        printf("\nEnter Last Name:");
        gets(e[i].name.ln);     
        printf("\nEnter Salary:");
        scanf("%d", &e[i].sal);     
        printf("\nEnter Date of Joining\n");
        scanf("%d", &e[i].DOJ.date);
        printf("\nEnter Month of Joining\n");
        scanf("%d", &e[i].DOJ.month);       
        printf("\nEnter Year of Joining\n");
        scanf("%d", &e[i].DOJ.year);
    }
    for(i=0; i<n; i++)  {
        printf("Code:%d\n", e[i].code);
        printf("First Name:%s\n", e[i].name.fn);
        printf("Last Name:%s\n", e[i].name.ln);
        printf("Salary:%d\n", e[i].sal);
        printf("Date of Joining:%d\n", e[i].DOJ.date);
        printf("Month of Joining:%d\n", e[i].DOJ.month);
        printf("Year of Joining:%d\n", e[i].DOJ.year);
    }
    getch();
}
