Array of Structure

We can use structure to store the value of one particular object but if we want to store the value of 100 such objects we need array of structure.

For eg: If we want to store the value of details of book like author, no of pages and price. We can define such structure as follows:

struct bookinfo{

    char[20] author;

    int pages;

    float price;

};

Now to define three similar structure we can define an array of the above defined structure as follows:

struct bookinfo record[3];

Lets's see this using a C program:

 #include
  struct bookinfo{
           char author[20];
           int pages;
           float price;
   };
 
   int main(){
       int i;
      struct bookinfo record[3];
      char suffix[3][3]={"st","nd","rd"};
      for(i=0;i<3 i="" p="">      {
             printf("Enter the author of first book: ");
             scanf("%s",record[i].author);
             printf("Enter the number of pages in the book: ");
             scanf("%d",&record[i].pages);
             printf("Enter the price of the book: ");
             scanf("%f",&record[i].price);
      }
 
      for(i=0;i<3 i="" p="">      {
 
         printf("\nThe author of %d%s book is: %s \n",i+1,suffix[i],record[i].author);
         printf("The number of pages in %d%s book is: %d \n",i+1,suffix[i],record[i].pages);
         printf("The price of %d%s book is: %f \n",i+1,suffix[i],record[i].price);
      }
      return 0;
  }

OUTPUT:

Enter the author of first book: fasdf
Enter the number of pages in the book: 32
Enter the price of the book: 34
Enter the author of first book: phy
Enter the number of pages in the book: 45
Enter the price of the book: 56.5
Enter the author of first book: math
Enter the number of pages in the book: 54
Enter the price of the book: 45.7

The author of 1st book is: fasdf
The number of pages in 1st book is: 32
The price of 1st book is: 34.000000

The author of 2nd book is: phy
The number of pages in 2nd book is: 45
The price of 2nd book is: 56.500000

The author of 3rd book is: math
The number of pages in 3rd book is: 54
The price of 3rd book is: 45.700001
