Question
A copy constructor is used to:Create a deep copy of an existing object.Modify an existing object.Call the destructor of another object.Access private members of another object.
Solution
A copy constructor is used to create a deep copy of an existing object. This means it creates a new object and copies all the fields of the existing object into the new one. This is useful when you want to create a duplicate of an object, but don't want the changes in the new object to affect the original one.
The copy constructor does not modify an existing object. It only reads the data from the existing object to create a new one.
The copy constructor does not call the destructor of another object. The destructor is a special function that is called when an object goes out of scope or is explicitly deleted. It is used to free up resources that the object may have acquired during its lifetime.
The copy constructor can access private members of another object of the same class. This is because it is a member function of the class, and member functions can access private members of the same class. However, it cannot access private members of an object of a different class.
