C++ : copy constructor

We already know the basic constructor utility which is : initializing internal members. If not constructor is specified, the default constructor initializes each of class' members with their constructor.

Now let's take a look to the copy constructor :

Point (const Point & p);

This constructor will initialize our object by copying another one :

Point p1 (otherPoint);

Note: It is also possible to define our own copy constructor to define more specifically which members should be copied.
