Behavior of delete this pointer in C++ -

i trying explore pointer in c++ . have created pointer class object , caling function delete current object behavior unexpected.

why output of last print statement x= 0 , y= 6.

#include<iostream> using namespace std;  class test { private:   int x;   int y; public:   test(int x = 6, int y = 6) { this->x = x; this->y = y; }   void setx(int a) { x = a; }   void sety(int b) { y = b; }   void destroy()  { delete this;   }   void print() { cout << "x = " << x << " y = " << y << endl; } };  int main() {    test *obj = new test();   test objs;   obj->print();   obj->destroy();    obj->print();   return 0; } 

deleting this legal , calls destructor of class

however, if object not allocated using new, undefined behavior

but have absolutely sure last member function invoked on object , none of of member function (after delete this line) gets called through this object, since this become dangling pointer, should not dereferenced.

if these, behavior undefined, can see in output.
