Array of structures

struct book
{
        int id;
        float price;
        char name[15];
};


int main()
{
    struct book b[2];

    for(i=0;i<2;i++)
    {
        printf("Enter id,price and name of the book");
        scanf("%d\t%f\t%s",&b[i].id,&b[i].price,b[i].name);
    }

    for(i=0;i<2;i++)
        printf("%d\t%f\t%s",b[i].id,b[i].price,b[i].name);

    return 0;
}

b = array of book structures
b[0] = 0th book structure in array b

We can access member of 0th book structure by b[0].member.
Generalizing it,we can access member of ith book structure of array b by

b[i].member
