Suppose we have to store data of 100 books we would be required to use 100 different structure variables from b1 to b100, which is definitely not very convenient. A better approach would be to use an array of structures.

Example (how to use an array of structures)

#include <stdio.h>
int main() {
	struct book {
		char name;
		int price;
		int pages;
	};
	struct book b[100];
	int i;
	for (i = 0; i <= 99; i++) {
		printf("\nEnter name, price and pages ");
		scanf("%c %d %d", &b[i].name, &b[i].price, &b[i].pages);
	}
	for (i = 0; i <= 99; i++)
		printf("\n%c %d %d", b[i].name, b[i].price, b[i].pages);

getchar();
return 0;
}
