This document discusses three topics in C++ programming: constructors, friend functions, and operator overloading. Constructors initialize objects and have the same name as the class. Friend functions can access private members of a class. Operator overloading gives special meanings to operators for user-defined types.

1. Constructor
2.Friend function
3. Operator overloading

2. CONSTRUCTOR
 A constructor is a “special” member function whose task is
to initialize the objects of its class.
 It is special because its name is the same as class name.A
Constructor is invoked whenever an object of it’s associate
class is created.
 EXAMPLE :

3.  They should be declared in the public section.
 They do not have any return types, not even void .
 EXAMPLE :

4. FRIEND FUNCTION
 In C++ a FRIEND FUNCTION that is a
“friend” of a given class is allowed access to
private and protected data in that class.
 A function can be made a friend function using
keyword friend.

5.  Any friend function is preceded with friend keyword.
 The declaration of friend function should be made
inside body of the class starting with keyword friend.
 SYNTAX :

6. OPERATOR OVERLOADING
 This means C++ has the ability to provide the operators
with a special meaning for a data type, this ability is
known as operator overloading.

7.  Almost any operator can be overloaded in
c++.However there are few operator which
can not be overloaded and they follows:
