Difference between virtual function and inline function in C++

A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions.Inline function: Inline function is a normal function which is defined by the keyword inline, it is a short function which is expanded by the compiler and its arguments are evaluated only once.

Virtual function:Virtual function is a member function which is declared within a base class and is redefined by a derived class.

Inline function:Inline function is a normal function which is defined by the keyword inline, it is a short function which is expanded by the compiler and its arguments are evaluated only once.

The syntax of defining the function inline in C++ is:

inline return-type function-name(parameters)
{
    // function code
} 

Difference between virtual function and inline function are as follows:

Virtual function

Inline function

1. Virtual function must be declared in public section of class.1. Inline function is a normal function which is defined by the keyword inline.2. Virtual function cannot be static.2. Inline function can also be non-static.3. Virtual function is defined in base class.3. Inline function are the short length functions that are automatically made the inline functions without using the inline keyword inside the class.4.

c++ difference between c++-virtual functions

C++ virtual function is a member function that is declared in the base class and redefined by a derived class. Virtual functions ensure that a correct function is called for the object, regardless of an expression used to make a function call.

<p>Other then the syntactical differences. The main difference is the way the this keyword behaves? In an arrow function, the this keyword remains the same throughout the life-cycle of the function and is always bound to the value of this in the...

In this article, we’ll take a look at using the strdup() function in C/C++. The strdup() function is very useful if you want to duplicate the contents of a string onto another string.

C++ Function is the block of organized, reusable code that can be used to perform the single, related action. The function performs a specific task.
