Write a c program to demonstrate nested structure

#include<stdio.h>

#include<conio.h>

struct date

{

int day;

int month;

int year;

};

void main()

{

struct employee

{

         int empid;

  struct date doj;

         float salary;

}e;

clrscr();

printf("Enter the employee id: ");

scanf("%d",&e.empid);

printf("Enter the Date of Joining: ");

scanf("%d%d%d",&e.doj.day,&e.doj.month,&e.doj.year);

printf("Enter the salary: ");

scanf("%f",&e.salary);

printf("Employee Information\n");

printf("Employee id=%d\n",e.empid);

printf("Employee Date of Joining=%d-%d-%d\n",e.doj.day,e.doj.month,e.doj.year);

printf("%f",e.salary);

getch();

}

Output:

Enter the employee id: 123

Enter the Date of Joining: 1 6 2005                                            

Enter the salary: 20000                                                         

Employee Information                                                           

Employee id=123                                                                

Employee Date of Joining=1-6-2005                                               

20000.000000

Write a c program to find the area of the room

#include<stdio.h>

#include<conio.h>

struct distance

{

         int feet;

         float inches;

};

struct room

{

  struct distance length;

  struct distance breadth;

};

void main()

{

struct room drawing;

float l,w;

clrscr();

drawing.length.feet=10;

drawing.length.inches=5.5;

drawing.breadth.feet=20;

drawing.breadth.inches=2.5;

l= drawing.length.feet+ drawing.length.inches/12;

w= drawing.breadth.feet+ drawing.breadth.inches/12;

printf("Area of the drawing room is %f",l*w,"square feet");

getch();

}

Output:

Area of the drawing room is 211.345486
