A virtual function is a member function declared in the base class using the 'virtual' keyword. 

We use virtual function to achieve runtime polymorphism.

We need a virtual function to ensure correct function is called for an object. For example, you can point a pointer to base class that refers to all derived objects. #codinglife #computerscience #software #coding #reactjs

But when base class pointer contains the address of the derived class object, it always executes the base class function. That's where a virtual function can be used to execute derived class function. Check out the code example below: #programmerhumor #learntocode
