Question

What is the problem of this program when I execute , I want class be destructed, but end of the program I see the error box after cout fetch.
What is the problem?

#include <iostream>
using namespace std;

class user {

    public:int internal;
    public:user(int point) {
               internal = point;
           };

           ~user () {
               cout << "Fetch";
           }
    };



void main() {
    user gil(5);
    user * p;
    p=&gil;
    delete p;
    getchar();
}

Try:

#include <iostream>
using namespace std;

class user 
{
public:
  int internal;
  user(int point) 
  {
    internal = point;
  }

  ~user() 
  {
    cout << "Fetch" << endl;
  }
};

int main() 
{
  user* p = new user(5);
  cout << p->internal << endl;
  delete p;
  return 0;
}

To avoid using new/delete and have the variable destructed when it falls out of scope:

#include <iostream>
using namespace std;

class user 
{
public:
  int internal;
  user(int point) 
  {
    internal = point;
  }

  ~user() 
  {
    cout << "Fetch" << endl;
  }
};

int main() 
{
  user p(5);
  cout << p.internal << endl;
  return 0;
}
