Hey, I'm reading now a C++ tutorial from cprogramming.com, lesson about a structures. And I see now and example of pointers in structures:And I'm confused about that part:Code:#include <iostream> using namespace std; struct xampl { int x; }; int main() { xampl structure; xampl *ptr; structure.x = 12; ptr = &structure; cout<< ptr->x; cin.get(); }
What for do we use that, if I just can writeCode:cout<< ptr->x;
instead of the pointer?Code:cout<<structure.x;
