this and arrow operator code example
Example: arrow operator c++
#include <iostream>

private:

public:

: x(x), y(y), name(name) {
printEntityPosition(this);
}
int getX() { return x; }
int getY() { return y; }
friend void printEntityPosition(Entity* e);
};
void printEntityPosition(Entity* e) {
cout << "Position: " << e->getX() << ", " << e->getY() << "\n";
}
int main() {
Entity* pointer = new Entity(1, 1, "Fred");
cout << (*pointer).name << "\n";
cout << pointer->name << "\n";
Entity not_a_pointer(2, 2, "Derf");
cout << not_a_pointer.name << "\n";
std::cin.get();
return 0;
