What is Structure

Structure in c is a user-defined data type that enables us to store the collection of different data types. Each element of a structure is called a member.

struct keyword is used to define the structure. Let's see the syntax to define the structure in c.

1.   struct structure_name   

2.   {  

3.       data_type member1;  

4.       data_type member2;  

5.       .  

6.       .  

7.       data_type memeberN;  

8.   };  

Let's see the example to define a structure for an entity employee in c.

1.   struct employee  

2.   {   int id;  

3.       char name[20];  

4.       float salary;  

5.   };  

Here, struct is the keyword; employee is the name of the structure; id, name, and salary are the members or fields of the structure.

Declaring structure variable

 declare variable at the time of defining the structure.

1.   struct employee  

2.   {   int id;  

3.       char name[50];  

4.       float salary;  

5.   }e1,e2;  

 

C Structure example

1.   #include<stdio.h>  

2.   #include <string.h>    

3.   struct employee      

4.   {   int id;      

5.       char name[50];      

6.   }e1;  //declaring e1 variable for structure    

7.   int main( )    

8.   {    

9.      //store first employee information    

10.                  e1.id=101;    

11.                  strcpy(e1.name, "Sonoo Jaiswal");//copying string into char array    

12.                  //printing first employee information    

13.                  printf( "employee 1 id : %d\n", e1.id);    

14.                  printf( "employee 1 name : %s\n", e1.name);    

15.               return 0;  

16.               }    

Output:

employee 1 id : 101

employee 1 name : Sonoo Jaiswal
