What is the difference between friend function and member function?

Friend function is a non-member function that has access to private and protected members of a class. It is not in the scope of the class in which it is declared. Member function is in scope of the class in which it is declared. ... A member function is called using object of the class.

How member function is different from normal function?

An ordinary function is nothing but a function with a return type and zero or more arguments. It can be called directly in the main or other functions. A member function is declared or defined within a class or structure. It is generally called with reference to the instance of the class or structure.

What is the difference between friend function and inline function explain with examples?

Answer: A friend function is used to access non public members of the class. A friend function cannot be called by class object. ... And the Inline functions are functions where the call is made to inline functions.

What is the difference between friend function and friend class?

Friend function is a function that is able to access the private and protected members of a class. In contrast, a friend class is a class which help in accessing the private members of a class. A friend function is declared by including its prototype inside the class, antecede it with the keyword friend.

What is the use of friend function?

In object-oriented programming, a friend function, that is a "friend" of a given class, is a function that is given the same access as methods to private and protected data. A friend function is declared by the class that is granting access, so friend functions are part of the class interface, like methods.

What are member functions?

Member functions are operators and functions that are declared as members of a class. Member functions do not include operators and functions declared with the friend specifier. These are called friends of a class. ... The definition of a member function is within the scope of its enclosing class.

What is a friend function in C++?

A friend function of a class is defined outside that class' scope but it has the right to access all private and protected members of the class. ... A friend can be a function, function template, or member function, or a class or class template, in which case the entire class and all of its members are friends.

What is the scope of non-member functions?

Non-member functions are instead declared outside any class (C++ calls this "at namespace scope"). (Non-static) member functions can also be virtual, but non-member functions (and static member functions) cannot.

How is a member function of a class defined?

A member function of a class is a function that has its definition or its prototype within the class definition like any other variable. It operates on any object of the class of which it is a member, and has access to all the members of a class for that object.

What is difference between inline function and normal function?

If a function is inline, the compiler places a copy of the code of that function at each point where the function is called at compile time. Normal functions do not have any such functionality.

What is the advantage of friend function in C++?

A friend function is used to access the non-public members of a class. It allows to generate more efficient code. It provides additional functionality which is not normally used by the class. It allows to share private class information by a non member function.

What is inline function give an example?

The inline functions are a C++ enhancement feature to increase the execution time of a program. Functions can be instructed to compiler to make them inline so that compiler can replace those function definition wherever those are being called.
