C++ Programming - OOPS Concepts - Discussion

We have a friend class and function, not any constructor.

Constructors are of three types:
* Default Constructor.
* Parametrized Constructor.
* Copy Constructor.

It's not a constructor.

Constructors are basically of 3 types:
1. Default Constructor (without arguments).
2. Parameterized Constructor (with arguments).
3. Copy Constructor.

It is a function called Friend Function.

Friend Function is used to access private members of two different classes for which it has been declared as a friend.

A constructor can not be defined outside the class so Friend constructor can't be define.

Note: There are main 3 types only.

1. Default.
2. Parameterless.
3. Parameterized.

Copy constructor is under Parameterized constructor.

Constructors, as we know have the same name as the class name. They can be three types of constructors namely:
1) Default constructor e.d constr() which has no parameters.
2) Parameterised constructors constr(x,y) that have some parameters passed to it.
3) Copy constructor constr(&object of constructor) that take input as the object of constructor type or rather copies the value of the constructor.

Friend functions exist but friend constructor don't exist in object oriented concept.

A friend is a function, but not a constructor.

All are type of constructor but friend is a type of function class type.

There are only 3 types of constructor.

Default, parameterized and copy constructor.

because friend are not constructors they are just used to access private data members of the classes.

Friend constructors are not possible because this is the function not a class which is used for accessing private data and member variables outside class.
