#include <stdio.h> struct Number{ int x, y; }; int main() { struct Number n1 = {4,5}; struct Number* ptr = &n1; printf("%d",ptr->x + ptr->y); return 0; } The structure just contains two variables. In the main method an instance of it is created which is n1. Then we have created a pointer of structure type and assigned it to the address of n1. So now ptr is pointing to the structure n1 and by using -> this operator we can access the values of x and y of n1. And by the way you try to predict the output.

you should start challenging, i remeber exactly this question i had to answer frequently: p->a equals (*p).a where p is pointer and a is usually a member of class/sfructure
