Polymorphism in object-oriented programming (OOP) is the ability of a single function or method to operate on multiple types of data. One common use of polymorphism in C++ is through the use of virtual functions. Here is an example: class Shape { public: virtual double area() = 0; }; class Rectangle: public Shape { private: […]
What’s overloading in OOP anyway? An example with C++.
In object-oriented programming (OOP), overloading refers to the ability of a class or its member functions to have multiple implementations with different parameters. An example of overloading in C++ would be a class called “Calculator” that has several different versions of a function called “add”: class Calculator { public: int add(int a, int b); double […]
What’s inheritance in OOP anyway? An example with C++.
### class Shape { public: double getArea() { return 0.0; } }; class Rectangle: public Shape { private: double width, height; public: Rectangle(double w, double h) { width = w; height = h; } double getArea() { return width * height; } }; int main() { Rectangle rect(3, 4); cout << “Area of rectangle: ” […]
