A friend function to a class may be declared or defined within the scope of class definition. The general syntax of a friend function declaration is given below;

friend return_type user_define_name(arguments list)

In above syntax friend is a keyword which informs the compiler that it is not member function of the class.

Return_type is the type of the value that the function returns.

User_define_name is the name of the function defined by the user,arguments list is the set of parameters defined inside the parenthesis.
