How would I go about destroying a declared class?.

my code.
CODE

#include <iostream>
using namespace std;
class Cat
{
      public:
             Cat(int intialAge); // Constructor
             ~Cat();              //deconstructor
             int GetAge() const;        //accessor function
             void SetAge(int age);      //accessor function
             void Meow() const;
      private:
              int itsAge;      //member variable
};

I declared
Cat boots(4);


How would I create a function or method to destroy class boots?

In your example you don't need to explicityly
delete the objects you created

when you create an automatic object like you did
the object will take care of deleting itself
when the object goes out of scope

For example
CODE

int main(void)
{
    Cat c1

    {
    // This object will delete
    // itself after the '}' below c2
    // because the inner scope will end
        Cat c2;
    }

    // c1 will be deleted when the
    // program exits
}


The only time you need to be concerned with
deleting an object explictly is when
you allocate the memory yourself

CODE

int main(void)
{
    // Create a cat object
    Cat *pCat = new Cat(4);

    ...

   // You need to delete the object
   // explicitly or you will have a
   // memory leak
   if(pCat) delete pCat;
}


cheers

That being said, garbage collection in C++ is usually suspect smile.gif
