C Structures

The structure is a user-defined data type in C, which is used to store a collection of different kinds of data.

  • The structure is something similar to an array; the only difference is array is used to store the same data types.
  • struct keyword is used to declare the structure in C.
  • Variables inside the structure are called members of the structure.

Defining a Structure in C

Syntax:
struct structureName
{
   //member definitions
};
Example:
struct Courses
{
   char  WebSite[50];
   char  Subject[50];
   int   Price;
};

Accessing Structure Members in C

Example:
#include<stdio.h>
#include<string.h>
 
struct Courses
{
   char  WebSite[50];
   char  Subject[50];
   int   Price;
};
 
void main( )
{
   struct Courses C;
   
   //Initialization
   strcpy( C.WebSite, "w3schools.in");
   strcpy( C.Subject, "The C Programming Language"); 
   C.Price = 0;
   
   //Print
   printf( "WebSite : %s\n", C.WebSite);
   printf( "Book Author : %s\n", C.Subject);
   printf( "Book Price : %d\n", C.Price);
}
Program Output:
WebSite : w3schools.in
