The virtual function is a member function that expects to be overridden in a derived class.
What is virtual function?
The object-oriented programming such a C++ program have a function to redefined in derived classes which is virtual function.
Virtual function will redefined or overridden the function from base class in derived class which is mean every time user pointer the base class to the object in derived class the function that will be use is the function in derived class.
For example with the code is,
class Base {
public:
void print() {
cout << "1" << endl;
}
};
class Derived : public Base {
public:
void print() {
cout << "2" << endl;
}
};
The result for the code is "1" because the function in base class is not a virtual function. If the code in base class change from function to virtual function the code will give the result "2".
