A copy constructor is a special constructor in the C++
programming language used to create a new object as a copy
of an existing object.
There are 3 important places where a copy constructor is
called.
When an object is created from another object of the same
type
When an object is passed by value as a parameter to a
function
When an object is returned from a function
class B //With copy constructor
{
private:
char *name;
public:
B()
{
name = new char[20];
}
~B()
{
delete name[];
}
//Copy constructor
B(const B &b)
{
name = new char[20];
strcpy(name, b.name);
}
};
