C++ Copy Constructor

#include <iostream>

class Copy
{
public:
    Copy(int x = 5, int y = 5); // default constructor
    Copy(const Copy& cp); // copy constructor
    void paste(); // member function
private:
    int x_, y_; // private variables to be declared
};

// default constructor definition
Copy::Copy(int x, int y)
{
    x_ = x;
    y_ = y;
}
// copy destructor definition
Copy::Copy(const Copy& cp)
{
    x_ = cp.x_;
    y_ = cp.y_;
}

// member function defintion
void Copy::paste()
{
    std::cout << x_ << std::endl << y_ << std::endl;
}

int main()
{
    // Try printing the original constructor first
    Copy original;
    original.paste();

    // Now we mae a new object and use the copy constructor
    // Basically, all we we did is made a object that copies another
    Copy newNumbers(30, 60);

    // Uncomment each method and see how each works!

    // method #1 - using assignment operator
    //Copy copier = newNumbers;

    // method #2 - passed as a value
    //Copy copier;
    //copier = Copy(newNumbers);

    // method #3 - copied explicitly
    //Copy copier(newNumbers);

    copier.paste();

    system("pause");
