destructor. friend, and copy constructor

I am working on a program and need to make a friend, deconstructor, and copy constructor.....


I was given this formula for the destructor and completely confused...

cout << value1 << value2

I also do not seem to see a whole lot of information on copy constructors and friends so was wanting to know if someone can help me in exactly what I have to do for these.....

Code:

---

#include<iostream>
#include<string>

using namespace std;

class Arithmetic

{
public:
        int Add(int num1, int num2);
        int Subtract(int num1, int num2);
        int Multiply(int num1, int num2);

private:
        int addedTotal, subtractedTotal, multipliedTotal;

};

//Adding the two numbers together
int Add(int num1, int num2)
{
        int addedTotal;
        addedTotal = num1 + num2;
        cout << endl << "The two numbers added together are: " << addedTotal;
        return addedTotal;
}

//Subtracting the two numbers together
int Subtract(int num1, int num2)
{
        int subtractedTotal;
        subtractedTotal = num1 - num2;
        cout << endl << endl << "Subtracting the first and second number give a difference of: " << subtractedTotal << endl ;
        return subtractedTotal;
}

//Multiplying the two numbers together
int Multiply(int num1, int num2)
{
        int multipliedTotal;
        multipliedTotal = num1 * num2;
        cout << endl << "Numbers 1 and 2 multiplied together give a product of: " << multipliedTotal << endl << endl;
        return multipliedTotal;
}       
       
int main()
{
        int num1, num2;
        cout << "Enter the first number: ";
        cin >> num1;
        cout << endl << "Enter the second number: ";
        cin >> num2;
        Add(num1, num2);
        Subtract(num1, num2);
        Multiply(num1, num2);
}

Code:

cout << value1 << value2

This has nothing to do with a destructor.

I am not getting your code.... what are you trying to do here....:(
You have declared the function in a class definition but defined it globally without class reference...

Also there is no class object created in main() to access these functions.... !!!

I suggest a good C++ book, http://www.codeguru.com/forum/showthread.php?t=231039.
