A Copy constructor is an overloaded constructor used to declare and initialize an object from another object.
Copy Constructor is of two types :
Default Copy constructor : The compiler defines the default copy constructor. If the user defines no copy constructor, compiler supplies its constructor.
User Defined constructor : The programmer defines the user-defined constructor.
Syntax Of User-defined Copy Constructor :
Class_name(const class_name &old_object);
Consider the following situation :
class A
{
A(A &x) // copy constructor.
{
// copyconstructor.
}
}
