Class destructors

A class destructor is called when the class instance is de-allocated

  • If the class was allocated with new, when delete is called, and

  • If allocated on the runtime stack (introduced in a block of statements), when the identifier goes out of scope. 

#include <iostream>

classs Point {
public:
    int x, y;

    Point(void) {
	cout << "constructor invoked" << endl;
    }

    ~Point(void) {
      cout << "destructor invoked" << endl;
    }
}
