OBJECT
Structures
THEORY
If we want a group of same data
type we use an array. If we want a group of elements ofdifferent data types we
use structures. For Example: To store the names, prices and number ofpages of a
book you can declare three variables. To store this information for more than
onebook three separate arrays may be declared. Another option is to make a
structure. No memory is allocated when a structure is declared. It simply
defines the “form” of thestructure. When a variable is made then memory is
allocated. This is equivalent to saying thatthere is no memory for “int” ,
but when we de clare an integer i.e.
is allocated.The structure for
the above mentioned case will look like
struct books
{
char bookname[20];
float price;
int pages;
};
struct book[50];
the above structure can hold
information of 50 books.

The
table consists of records of employees of an organization.
Section-A
(a)
Write a program in “C” to input
records through keyboard and store them in a structure array called Employee.
Ans:
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
struct employee
{
char name;
char post;
char city;
int phone;
float sallary;
};
clrscr();
struct employee emp[10];
int i;
for(i=0;i<10;i++)
{
printf("\nEnter the
name,post,city,phone No. and sallary\n");
scanf("%s%s%s%f%d",&emp[i].name,&emp[i].post,&emp[i].city,&emp[i].phone,&emp[i].sallary);
}
}
linkfloat()
{
float a=0,*b;
b=&a;
a=*b;
return a;
}
(b)
Write a function to display the
list of all Records.
Ans:
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
