structure in c

-
//structures are user defined data types in c
//in structures we can store any type of data types like int floate char etc

//declaring a structure
#include <stdio.h>
#include <string.h>
struct library //here strut is a keyword for creating a structure, here library also called structure tag
{
    char name[20]; //members or elements of library tag or structure name
    int pages;
    char author[20];//character array or string of size 20, we have to use string for a char value
//there are two methods to initialize a variable from structure
}; //book1; //method 1
int main()
{
    struct library book1,book2; //method 2
    //there are two ways to assign values to the variables
    //struct library book1={'h',2,'s'}; //way 1,but this is an error, like this we can only assign int values not char
    strcpy(book1.name,"softwareharish"); //way 2
    book1.pages=100;
    strcpy(book1.author,"N Harish");//for assigning a char value we have to use strcpy() from <string.h>
    //accessing structure members
    printf("name of the book:%s\n",book1.name); //here dot (.) is called structure member operator
    printf("author of the book:%s\n",book1.author);
    printf("number of pages of the book:%d",book1.pages);
    return 0;
}
