[RESOLVED] Class help using constructors and destructors.

bake.cpp

Code:

---

#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;
class Walnut
{
public:
        int Size;
};
class Squirrel
{
private:
        Walnut *MyDinner;
public:
        Squirrel();
        ~Squirrel();
};
Squirrel::Squirrel()
{
        cout << "Starting!" << endl;
        MyDinner = new Walnut;
        MyDinner->Size = 30;
}
Squirrel::Squirrel()
{
        cout << "Cleaning up my mess!" << endl;
        delete MyDinner;
}
int main()
{
        Squirrel *Sam = new Squirrel;
        Squirrel *Sally = new Squirrel;
        delete Sam;
        delete Sally;
        system("pause");
                return 0;
}

and my error code

The problem is that you defined the destructor wrongly. You defined it such that it is the default constructor, which was already defined. Rather:

Code:

---

Squirrel::~Squirrel()
{
        cout << "Cleaning up my mess!" << endl;
        delete MyDinner;
}

---

By the way, note that you should define the copy constructor and copy assignment operator too (or declare them private), but I presume that that exercise comes later.

Thank you so much! I appreciate the help greatly :) you resolved the problem for me, and I will be sure to remember that!
