Structure

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 employeen”  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();  }
