C++: Operator Overloading vs Inheritance

What is the difference between operator overloading and inheritance in C++?

Operator overloading allows you to define custom behavior for operators, while inheritance enables a class to inherit properties and methods from another class.

Can you give me an example of operator overloading?

Sure! For instance, you can overload the '+' operator to add two objects of a class together, like this:

class Complex {
public:
    int real, imag;
    Complex operator+(const Complex &obj) {
        Complex temp;
        temp.real = real + obj.real;
        temp.imag = imag + obj.imag;
        return temp;
    }
};

How does inheritance work in C++?

Inheritance allows a class (derived class) to inherit attributes and methods from another class (base class). This promotes code reusability.

Which one is better to use in a project?

It depends on the use case. Use operator overloading for custom operations on objects and inheritance for creating a hierarchy of classes.
