Array of Structures in C

Array of Structures:

• Using structure variable we can store only one record.
• To store multiple records, we need to declare Array variable of structure type.
• We use loop to process elements of these records.

struct Emp
{
	....
	....
};
struct Emp e;   -> can store only 1 record
struct Emp e1, e2, e3; -> can store upto 3 records
struct Emp arr[100]; -> can store 100 records

#include<stdio.h>
struct Emp
{
	int id;
	char name[20];
	float salary;
};
int main()
{
	struct Emp arr[3];
	int i;
	
	printf("Enter 3 Emp records : \n");
	for(i=0 ; i<3 ; i++)
	{
		printf("Enter Emp-%d details : \n", i+1);	
		scanf("%d%s%f", &arr[i].id, arr[i].name, &arr[i].salary);
	}
	printf("Employee details are : \n");
	for(i=0 ; i<3 ; i++)
	{
		printf("%d \t %s \t %f \n", arr[i].id, arr[i].name, arr[i].salary);
	}
	return 0;
}
