Challenge 3: Implement a Calculator Class

Explore how to implement a Calculator class in C++ with private variables and member functions for basic arithmetic operations. Understand class design, encapsulation, and constructors by creating and using an object to perform calculations. This lesson helps you practice essential OOP principles through a practical coding challenge.

We'll cover the following...

Problem Statement

Write a C++ class called Calculator with

  • private member variables:

    • num1 and num2 (float type)

And member functions:

  • add(float n1, float n2), a function which returns the addition of two numbers

  • Subtract(float n1, float n2), a function ...
