Structure is the collection of different data types. It allocates memory for the highest data items. We can access more than one element at a time of all items. We can access the elements of structure by using dot (.) operator in case of normal variable or by using (→) arrow operator in case of pointer.
//Demonstration of structure
struct student s;
printf("Enter the name, rall no., and age of a student ");
