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++ 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.
C/C++ problems. If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends.
