Data Structures 

A structure is a composite data type that defines a grouped list of variables that are to be placed under one name in a block of memory. It allows different variables to be accessed by using a single pointer to the structure.

Syntax

struct structure_name   

{  

    data_type member1;  

    data_type member2;  

    .  

    .  

    data_type memeber;  

};  

Advantages

• It can hold variables of different data types.
• We can create objects containing different types of attributes.
• It allows us to re-use the data layout across programs.
• It is used to implement other data structures like linked lists, stacks, queues, trees, graphs etc.

Program

 #include<stdio.h>  

#include<conio.h>  

void main( )  

{  

struct employee  

{  

int id ;  

float salary ;  

int mobile ;  

} ;  

struct employee e1,e2,e3 ;  

clrscr();  

printf ("\nEnter ids, salary & mobile no. of 3 employee\n"  

scanf ("%d %f %d", &e1.id, &e1.salary, &e1.mobile);  

scanf ("%d%f %d", &e2.id, &e2.salary, &e2.mobile);  

scanf ("%d %f %d", &e3.id, &e3.salary, &e3.mobile);  

printf ("\n Entered Result ");  

printf ("\n%d %f %d", e1.id, e1.salary, e1.mobile);  

printf ("\n%d%f %d", e2.id, e2.salary, e2.mobile);  

printf ("\n%d %f %d", e3.id, e3.salary, e3.mobile);  

getch();  

}
