Multilevel Inheritance
A class can also be derived from one class, which is already derived from another class.
In the following example, MyGrandChild is derived from class MyChild (which is derived from MyClass).
Example
// Base class (parent)
class MyClass {
public:
void
myFunction() {
cout << "Some content in parent class." ;
}
};
//
Derived
class (child)
class MyChild: public MyClass {
};
// Derived class
(grandchild)
class MyGrandChild: public MyChild {
};
int main() {
MyGrandChild myObj;
myObj.myFunction();
return 0;
}
