printing using structures & use of struct pointers

#include<stdio.h>
#include<string.h>
struct Book input();
void display(struct Book b);
struct Book 
{
    int bookid;
    char title[20];
    float price;
};
int main()
{
    struct Book b1= {1,"Two bottles", 250.0};
    struct Book b2,b3;
    b2.bookid= 2;
    strcpy(b2.title,"Outliers");
    b2.price= 300.0;
    b3=input();
    display(b1);
    display(b2);
    display(b3);
    return 0;
}
struct Book input()
{
    struct Book b;
    printf("Enter bookid, title, price: ");
    scanf("%d",&b.bookid);
    fgets(b.title,20,stdin);
    b.title[strlen(b.title)-1]='\0';
    scanf("%f",&b.price);
    return b;
}
void display(struct Book b)
{
    printf("\n%d  %s  %f",b.bookid, b.title, b.price);
}



use of struct pointers



#include<stdio.h>
struct person
{
    char name[50];
    int age;
    int income;
};

int main()
{
    struct person A={"Yash",32,50000};
    struct person *P=&A;
    printf ("Name: %s\n", (*P).name);
    printf("Age: %d\n", P->age);
    printf("Income: %d\n", P->income);

}
